Cest pas encore gagné mais j'ai biaisé (provisoire) en copiant les liens de 18.04 et collé dans le home de 20.04, le souci est que Gimp les vois pas.
J'ai installé l'imprimante en 5 mn et réseau (comme d'hab) avec le "bundle" de Juillet 2015 qui a opéré sous 14.04, 18.04 Hugin, VLC, LibreOffice en français, le dernier Qarte et demain j'attaque le scanner; le terminal est assez rigolot avec son format 16:9 et les lignes dans un style (pas police) tout étiré.
C'est tout pour aujourd'hui.

Bravo !

le souci est que Gimp les voit pas.

Ça, c'est probablement la magie des snap...
Si c'est bien ça, il faut désinstaller le snap de Gimp, puis le réinstaller avec l'option ad hoc.
Vois snap, et cherche "confinement" : elle y figure.

La seconde ligne est claire et après avoir lancé gimp le problème d'ouverture d'image persiste mais dû probablement à l'actuel Nautilus que je dois conformer comme à partir d ici https://forum.ubuntu-fr.org/viewtopic.p … #p22017795 mais je rame; n'étant pas pris par l'urgence nous verrons bien à la sortie de 20.04.1 en Juillet.

moko138 · Le 07/05/2020, à 11:37

Bizarre, que l'option --classic ait été ignorée !

Vu

man snap   ## de Bionic
       --devmode
              Put snap in development mode and disable security confinement

       --classic
              Put snap in classic mode and disable security confinement

peut-être pourrais-tu désinstaller et réinstaller avec l'option --devmode, mais j'en ignore les conséquences.

Autres possibilités :
- demander à d'autres utilisateurs de 20.04,
- quand tu as une image à traiter, tu la déplaces momentanément dans ton home.

Que retourne

snap(8)                     System Manager's Manual                    snap(8)

NAME
       snap - Tool to interact with snaps

SYNOPSIS
       snap [OPTIONS]

DESCRIPTION
       The snap command lets you install, configure, refresh and remove snaps.
       Snaps are packages that work across many different Linux distributions,
       enabling  secure  delivery  and operation of the latest apps and utili‐
       ties.

OPTIONS
COMMANDS
   abort
       Abort a pending change

       The abort command attempts to abort a change  that  still  has  pending
       tasks.

       Usage: snap abort [abort-OPTIONS]

       --last Select last change of given type (install, refresh, remove, try,
              auto-refresh, etc.). A question mark at  the  end  of  the  type
              means to do nothing (instead of returning an error) if no change
              of the given type is found. Note the question  mark  could  need
              protecting from the shell.

   ack
       Add an assertion to the system

       The ack command tries to add an assertion to the system assertion data‐
       base.

       The assertion may also be a newer revision of a pre-existing  assertion
       that it will replace.

       To  succeed  the assertion must be valid, its signature verified with a
       known public key and the assertion consistent with and its prerequisite
       in the database.

   alias
       Set up a manual alias

       The  alias  command  aliases  the  given  snap application to the given
       alias.

       Once this manual alias is setup the respective application command  can
       be invoked just using the alias.

       Usage: snap alias [alias-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

   aliases
       List aliases in the system

       The aliases command lists all aliases available in the system and their
       status.

       $ snap aliases <snap>

       Lists only the aliases defined by the specified snap.

       An alias noted as undefined means it was explicitly enabled or disabled
       but is not defined in the current revision of the snap, possibly tempo‐
       rarily  (e.g.   because of a revert). This can cleared with 'snap alias
       --reset'.

   changes
       List system changes

       The changes command displays a summary of system changes performed  re‐
       cently.

       Usage: snap changes [changes-OPTIONS]

       --abs-time
              Display  absolute times (in RFC 3339 format). Otherwise, display
              relative times up to 60 days, then YYYY-MM-DD.

   check-snapshot
       Check a snapshot

       The check-snapshot command verifies the user, system and  configuration
       data of the snaps included in the specified snapshot.

       The  check  operation runs the same data integrity verification that is
       performed when a snapshot is restored.

       By default, this command checks all the data in a  snapshot.   Alterna‐
       tively,  you can specify the data of which snaps to check, or for which
       users, or a combination of these.

       If a snap is included in a check-snapshot operation, excluding its sys‐
       tem  and  configuration  data from the check is not currently possible.
       This restriction may be lifted in the future.

       Usage: snap check-snapshot [check-snapshot-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

       --users
              Check  data  of  only specific users (comma-separated) (default:
              all users)

   connect
       Connect a plug to a slot

       The connect command connects a plug to a slot.  It may be called in the
       following ways:

       $ snap connect <snap>:<plug> <snap>:<slot>

       Connects the provided plug to the given slot.

       $ snap connect <snap>:<plug> <snap>

       Connects  the  specific plug to the only slot in the provided snap that
       matches the connected interface. If more than one  potential  slot  ex‐
       ists, the command fails.

       $ snap connect <snap>:<plug>

       Connects  the  provided  plug  to the slot in the core snap with a name
       matching the plug name.

       Usage: snap connect [connect-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

   connections
       List interface connections

       The  connections  command  lists connections between plugs and slots in
       the system.

       Unless <snap> is provided, the listing is for connected plugs and slots
       for  all snaps in the system. In this mode, pass --all to also list un‐
       connected plugs and slots.

       $ snap connections <snap>

       Lists connected and unconnected plugs and slots for the specified snap.

       Usage: snap connections [connections-OPTIONS]

       --all  Show connected and unconnected plugs and slots

   create-cohort
       Create cohort keys for a series of snaps

       The create-cohort command creates a set of cohort keys for a given  set
       of snaps.

       A  cohort  is  a  view or snapshot of a snap's "channel map" at a given
       point in time that fixes the set of revisions for the snap given  other
       constraints  (e.g. channel or architecture). The cohort is then identi‐
       fied by an opaque per-snap key that works across systems. Installations
       or refreshes of the snap using a given cohort key would use a fixed re‐
       vision for up to 90 days, after which a new set of revisions  would  be
       fixed under that same cohort key and a new 90 days window started.
       
          disable
       Disable a snap in the system

       The  disable  command disables a snap. The binaries and services of the
       snap will no longer be available, but all the data is  still  available
       and the snap can easily be enabled again.

       Usage: snap disable [disable-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

   disconnect
       Disconnect a plug from a slot

       The disconnect command disconnects a plug  from  a  slot.   It  may  be
       called in the following ways:

       $ snap disconnect <snap>:<plug> <snap>:<slot>

       Disconnects the specific plug from the specific slot.

       $ snap disconnect <snap>:<slot or plug>

       Disconnects  everything  from the provided plug or slot.  The snap name
       may be omitted for the core snap.

       Usage: snap disconnect [disconnect-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

   download
       Download the given snap

       The download command downloads the given snap and its supporting asser‐
       tions to the current directory with .snap and .assert file  extensions,
       respectively.

       Usage: snap download [download-OPTIONS]

       --channel
              Use this channel instead of stable

       --edge Install from the edge channel

       --beta Install from the beta channel

       --candidate
              Install from the candidate channel

       --stable
              Install from the stable channel

       --revision
              Download  the  given  revision of a snap, to which you must have
              developer access

       --basename
              Use this basename for the snap and assertion files (defaults  to
              <snap>_<revision>)

       --target-directory
              Download to this directory (defaults to the current directory)

       --cohort
              Download from the given cohort

   enable
       Enable a snap in the system

       The enable command enables a snap that was previously disabled.

       Usage: snap enable [enable-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

   find
       Find packages to install

       The find command queries the store for available packages.

       With the --private flag, which requires the user to be logged-in to the
       store  (see  'snap  help login'), it instead searches for private snaps
       that the user has developer access to, either directly or  through  the
       store's collaboration feature.

       A  green check mark (given color and unicode support) after a publisher
       name indicates that the publisher has been verified.

       Usage: snap find [find-OPTIONS]

       Aliases: search

       --private
              Search private snaps.

       --narrow
              Only search for snaps in “stable”.

       --section  [="show-all-sections-please"]  <default:  "no-section-speci‐
       fied">
              Restrict the search to a given section.

       --color <default: "auto">
              Use a little bit of color to highlight some things.

       --unicode <default: "auto">
              Use a little bit of Unicode to improve legibility.

   forget
       Delete a snapshot

       The  forget  command  deletes a snapshot. This operation can not be un‐
       done.

       A snapshot contains archives for the  user,  system  and  configuration
       data of each snap included in the snapshot.

       By  default, this command forgets all the data in a snapshot.  Alterna‐
       tively, you can specify the data of which snaps to forget.

       Usage: snap forget [forget-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

   get
       Print configuration options

       The get command prints configuration options for the provided snap.

           $ snap get snap-name username
           frank

       If multiple option names are provided, the corresponding values are re‐
       turned:

           $ snap get snap-name username password
           Key       Value
           username  frank
           password  ...

       Nested values may be retrieved via a dotted path:

           $ snap get snap-name author.name
           frank

       Usage: snap get [get-OPTIONS]

       -t     Strict typing with nulls and quoted strings

       -d     Always return document, even with single key

       -l     Always return list, even with single key

   help
       Show help about a command

       The help command displays information about snap commands.

       Usage: snap help [help-OPTIONS]

       --all  Show a short summary of all commands

   info
       Show detailed information about snaps

       The info command shows detailed information about snaps.
              The snaps can be specified by name or by path;  names  are  looked  for
       both  in  the  store  and  in the installed snaps; paths can refer to a
       .snap file, or to a directory that contains an unpacked  snap  suitable
       for  'snap  try'  (an  example  of  this would be the 'prime' directory
       snapcraft produces).

       Usage: snap info [info-OPTIONS]

       --color <default: "auto">
              Use a little bit of color to highlight some things.

       --unicode <default: "auto">
              Use a little bit of Unicode to improve legibility.

       --abs-time
              Display absolute times (in RFC 3339 format). Otherwise,  display
              relative times up to 60 days, then YYYY-MM-DD.

       --verbose
              Include more details on the snap (expanded notes, base, etc.)

   install
       Install snaps on the system

       The install command installs the named snaps on the system.

       To  install  multiple  instances of the same snap, append an underscore
       and a unique identifier (for each instance) to a snap's name.

       With no further options, the snaps are installed  tracking  the  stable
       channel, with strict security confinement.

       Revision  choice  via  the --revision override requires the the user to
       have developer access to the  snap,  either  directly  or  through  the
       store's  collaboration feature, and to be logged in (see 'snap help lo‐
       gin').

       Note a later refresh will typically undo a  revision  override,  taking
       the snap back to the current revision of the channel it's tracking.

       Use --name to set the instance name when installing from snap file.

       Usage: snap install [install-OPTIONS]
       --color <default: "auto">
              Use a little bit of color to highlight some things.

       --unicode <default: "auto">
              Use a little bit of Unicode to improve legibility.

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

       --channel
              Use this channel instead of stable

       --edge Install from the edge channel

       --beta Install from the beta channel

       --candidate
              Install from the candidate channel

       --stable
              Install from the stable channel

       --devmode
              Put snap in development mode and disable security confinement

       --jailmode
              Put snap in enforced confinement mode

       --classic
              Put snap in classic mode and disable security confinement

       --revision
              Install the given revision of a snap, to which you must have de‐
              veloper access

       --dangerous
              Install  the  given  snap file even if there are no pre-acknowl‐
              edged signatures for it, meaning it was not verified  and  could
              be dangerous (--devmode implies this)

       --unaliased
              Install the given snap without enabling its automatic aliases

       --name Install the snap file under the given instance name
              --cohort
              Install the snap in the given cohort

   interface
       Show details of snap interfaces

       The interface command shows details of snap interfaces.

       If  no  interface  name  is provided, a list of interface names with at
       least one connection is shown, or a list of all interfaces if --all  is
       provided.

       Usage: snap interface [interface-OPTIONS]

       --attrs
              Show interface attributes

       --all  Include unused interfaces

   known
       Show known assertions of the provided type

       The  known  command  shows  known  assertions of the provided type.  If
       header=value pairs are provided after the assertion  type,  the  asser‐
       tions  shown must also have the specified headers matching the provided
       values.

       Usage: snap known [known-OPTIONS]

       --remote
              Query the store for the assertion, via snapd if possible

       --direct
              Query the store for the assertion, without attempting to go  via
              snapd

   list
       List installed snaps

       The  list  command displays a summary of snaps installed in the current
       system.

       A green check mark (given color and unicode support) after a  publisher
       name indicates that the publisher has been verified
              Usage: snap list [list-OPTIONS]

       --all  Show all revisions

       --color <default: "auto">
              Use a little bit of color to highlight some things.

       --unicode <default: "auto">
              Use a little bit of Unicode to improve legibility.

   login
       Authenticate to snapd and the store

       The  login  command authenticates the user to snapd and the snap store,
       and saves credentials into the ~/.snap/auth.json file. Further communi‐
       cation with snapd will then be made using those credentials.

       It's not necessary to log in to interact with snapd. Doing so, however,
       enables purchasing of snaps using 'snap buy', as well as some some  de‐
       veloper-oriented features as detailed in the help for the find, install
       and refresh commands.

       An account can be set up at https://login.ubuntu.com

   logout
       Log out of snapd and the store

       The logout command logs the current user out of snapd and the store.

   logs
       Retrieve logs for services

       The logs command fetches logs of the given services and  displays  them
       in chronological order.

       Usage: snap logs [logs-OPTIONS]

       -n <default: "10">
              Show only the given number of lines, or 'all'.

       -f     Wait for new lines and print them as they come in.

   model
       Get the active model for this device
       The  model  command  returns the active model assertion information for
       this device.

       By default, only the essential model identification information is  in‐
       cluded in the output, but this can be expanded to include all of an as‐
       sertion's non-meta headers.

       The verbose output is presented in a structured, yaml-like format.

       Similarly, the active serial assertion can be used for the  output  in‐
       stead of the model assertion.

       Usage: snap model [model-OPTIONS]

       --abs-time
              Display  absolute times (in RFC 3339 format). Otherwise, display
              relative times up to 60 days, then YYYY-MM-DD.

       --color <default: "auto">
              Use a little bit of color to highlight some things.

       --unicode <default: "auto">
              Use a little bit of Unicode to improve legibility.

       --serial
              Print the serial assertion instead of the model assertion.

       --verbose
              Print all specific assertion fields.

       --assertion
              Print the raw assertion.

   okay
       Acknowledge warnings

       The okay command acknowledges the warnings listed with 'snap warnings'.

       Once acknowledged a warning won't appear again unless it re-occurrs and
       sufficient time has passed.

   pack
       Pack the given directory as a snap
       
              The  pack command packs the given snap-dir as a snap and writes the re‐
       sult to target-dir. If target-dir is omitted, the result is written  to
       current  directory.  If both source-dir and target-dir are omitted, the
       pack command packs the current directory.

       The default file name for a snap  can  be  derived  entirely  from  its
       snap.yaml, but in some situations it's simpler for a script to feed the
       filename in. In those cases, --filename can be given  to  override  the
       default.  If this filename is not absolute it will be taken as relative
       to target-dir.

       When used with --check-skeleton, pack only checks whether snap-dir con‐
       tains  valid  snap  metadata and raises an error otherwise. Application
       commands listed in snap metadata file,  but  appearing  with  incorrect
       permission  bits  result  in  an  error. Commands that are missing from
       snap-dir are listed in diagnostic messages.

       Usage: snap pack [pack-OPTIONS]

       --check-skeleton
              Validate snap-dir metadata only

       --filename
              Output to this filename

   prefer
       Enable aliases from a snap, disabling any conflicting aliases

       The prefer command enables all aliases of the given snap in  preference
       to  conflicting  aliases  of other snaps whose aliases will be disabled
       (or removed, for manual ones).

       Usage: snap prefer [prefer-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.
              
                 prepare-image
       Prepare a device image

       The prepare-image command performs some of the steps necessary for cre‐
       ating device images.

       For core images it is not invoked directly but usually  via  ubuntu-im‐
       age.

       For preparing classic images it supports a --classic mode

       Usage: snap prepare-image [prepare-image-OPTIONS]

       --classic
              Enable classic mode to prepare a classic model image

       --arch Specify  an  architecture for snaps for --classic when the model
              does not

       --channel
              The channel to use

       --snap <snap>[=<channel>]
              Include the given snap from the store or  a  local  file  and/or
              specify the channel to track for the given snap

   refresh
       Refresh snaps in the system

       The  refresh  command  updates the specified snaps, or all snaps in the
       system if none are specified.

       With no further options, the snaps are refreshed to the  current  revi‐
       sion  of the channel they're tracking, preserving their confinement op‐
       tions.

       Revision choice via the --revision override requires the  the  user  to
       have  developer  access  to  the  snap,  either directly or through the
       store's collaboration feature, and to be logged in (see 'snap help  lo‐
       gin').

       Note a later refresh will typically undo a revision override.
       
              Usage: snap refresh [refresh-OPTIONS]

       --color <default: "auto">
              Use a little bit of color to highlight some things.

       --unicode <default: "auto">
              Use a little bit of Unicode to improve legibility.

       --abs-time
              Display  absolute times (in RFC 3339 format). Otherwise, display
              relative times up to 60 days, then YYYY-MM-DD.

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

       --time Show auto refresh information but do not perform a refresh

       --ignore-validation
              Ignore validation by other snaps blocking the refresh

   remove
       Remove snaps from the system

       The remove command removes the named snap instance from the system.

       By default all the snap revisions are removed, including their data and
       the common data directory. When a --revision option is passed only  the
       specified revision is removed.

       Usage: snap remove [remove-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

       --revision
              Remove only the given revision

       --purge
              Remove the snap without saving a snapshot of its data

   restart
       Restart services

       The restart command restarts the given services.

       If the --reload option is given, for  each  service  whose  app  has  a
       reload command, a reload is performed instead of a restart.

       Usage: snap restart [restart-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

       --reload
              If the service has a reload command, use it instead of  restart‐
              ing.

   restore
       Restore a snapshot

       The restore command replaces the current user, system and configuration
       data of included snaps, with the corresponding data from the  specified
       snapshot.

       By default, this command restores all the data in a snapshot.  Alterna‐
       tively, you can specify the data of which  snaps  to  restore,  or  for
       which users, or a combination of these.

       If  a snap is included in a restore operation, excluding its system and
       configuration data from the restore is not currently possible. This re‐
       striction may be lifted in the future.

       Usage: snap restore [restore-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.
              
                     --users
              Restore data of only specific users (comma-separated)  (default:
              all users)

   revert
       Reverts the given snap to the previous state

       The  revert command reverts the given snap to its state before the lat‐
       est refresh. This will reactivate the previous snap revision, and  will
       use  the original data that was associated with that revision, discard‐
       ing any data changes that were done by the latest revision. As  an  ex‐
       ception,  data  which the snap explicitly chooses to share across revi‐
       sions is not touched by the revert process.

       Usage: snap revert [revert-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

              Revert to the given revision
              
                 run
       Run the given snap command

       The run command executes the given snap command with the right confine‐
       ment and environment.

       Usage: snap run [run-OPTIONS]

       --shell
              Run a shell instead of the command (useful for debugging)

       --strace [="with-strace"] <default: "no-strace">
              Run the command  under  strace  (useful  for  debugging).  Extra
              strace  options  can  be  specified  as well here. Pass --raw to
              strace early snap helpers.

       --gdb  Run the command with gdb

       --trace-exec
              Display exec calls timing data

   save
       Save a snapshot of the current data

       The save command creates a snapshot of the  current  user,  system  and
       configuration data for the given snaps.

       By  default,  this  command  saves the data of all snaps for all users.
       Alternatively, you can specify the data of which snaps to save, or  for
       which users, or a combination of these.

       If  a  snap  is  included in a save operation, excluding its system and
       configuration data from the snapshot is not  currently  possible.  This
       restriction may be lifted in the future.

       Usage: snap save [save-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

       --abs-time
              Display absolute times (in RFC 3339 format). Otherwise,  display
              short relative times.

       --users
              Snapshot data of only specific users (comma-separated) (default:
              all users)

   saved
       List currently stored snapshots

       The saved command displays a list of snapshots that have  been  created
       previously with the 'save' command.

       Usage: snap saved [saved-OPTIONS]

       --abs-time
              Display  absolute times (in RFC 3339 format). Otherwise, display
              short relative times.

       --id   Show only a specific snapshot.

   services
       Query the status of services

       The services command lists information about the services specified, or
       about the services in all currently installed snaps.

   set
       Change configuration options

       The  set  command  changes  the  provided  configuration options as re‐
       quested.

           $ snap set snap-name username=frank password=$PASSWORD

       All configuration changes are persisted at once,  and  only  after  the
       snap's configuration hook returns successfully.

       Nested values may be modified via a dotted path:

           $ snap set snap-name author.name=frank
           
                  Configuration option may be unset with exclamation mark:
           $ snap set snap-name author!

       Usage: snap set [set-OPTIONS]

       --no-wait

       Usage: snap start [start-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

       --enable
              As  well  as  starting  the  service  now,  arrange for it to be
              started on boot.

   stop
       Stop services

       The stop command stops, and optionally disables, the given services.

       Usage: snap stop [stop-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

       --disable
              As well as stopping the service now, arrange for it to no longer
              be started on boot
              
                 switch
       Switches snap to a different channel

       The switch command switches the given snap to a different channel with‐
       out doing a refresh.

       Usage: snap switch [switch-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

       --channel
              Use this channel instead of stable

       --edge Install from the edge channel

       --beta Install from the beta channel

       --candidate

              Switch the snap into the given cohort

       --leave-cohort
              Switch the snap out of its cohort
              
                 tasks
       List a change's tasks

       The tasks command displays a summary of tasks associated with an  indi‐
       vidual change.

       Usage: snap tasks [tasks-OPTIONS]

       Aliases: change

       --abs-time
              Display  absolute times (in RFC 3339 format). Otherwise, display
              relative times up to 60 days, then YYYY-MM-DD.

       --last Select last change of given type (install, refresh, remove, try,
              auto-refresh,  etc.).  A  question  mark  at the end of the type
              means to do nothing (instead of returning an error) if no change
              of  the  given  type is found. Note the question mark could need
              protecting from the shell.

   try
       Test an unpacked snap in the system

       The try command installs an unpacked snap into the system  for  testing
       purposes.   The  unpacked  snap content continues to be used even after
       installation, so non-metadata changes there go live instantly. Metadata
       changes  such  as those performed in snap.yaml will require reinstalla‐
       tion to go live.

       If snap-dir argument is omitted, the try command will attempt to  infer
       it  if either snapcraft.yaml file and prime directory or meta/snap.yaml
       file can be found relative to current working directory.

       Usage: snap try [try-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

       --devmode
              Put snap in development mode and disable security confinement

       --jailmode

       --classic
              Put snap in classic mode and disable security confinement

   unalias
       Remove a manual alias, or the aliases for an entire snap

       The  unalias command removes a single alias if the provided argument is
       a manual alias, or disables all aliases of  a  snap,  including  manual
       ones, if the argument is a snap name.

       Usage: snap unalias [unalias-OPTIONS]

       --no-wait
              Do  not  wait  for  the  operation  to finish but just print the
              change id.

   unset
       Remove configuration options

       The unset command removes the provided  configuration  options  as  re‐
       quested.

            $ snap unset snap-name name address

       All  configuration  changes  are  persisted at once, and only after the
       snap's configuration hook returns successfully.

       Nested values may be removed via a dotted path:

            $ snap unset snap-name user.name

       Usage: snap unset [unset-OPTIONS]

       --no-wait
              Do not wait for the operation  to  finish  but  just  print  the
              change id.

   version
       Show version details

       The  version  command  displays  the  versions  of  the running client,
       server, and operating system.

   warnings
       List warnings

       The warnings command lists the warnings that have been reported to  the
       system.

       Once warnings have been listed with 'snap warnings', 'snap okay' may be
       used to silence them. A warning that's been silenced in this  way  will
       not  be listed again unless it happens again, _and_ a cooldown time has
       passed.

       Warnings expire automatically, and once expired they are forgotten.

       Usage: snap warnings [warnings-OPTIONS]

       --abs-time
              Display absolute times (in RFC 3339 format). Otherwise,  display
              relative times up to 60 days, then YYYY-MM-DD.

       --all  Show all warnings

       --verbose
              Show more information

   watch
       Watch a change in progress

       The  watch  command  waits  for the given change-id to finish and shows
       progress (if available).

       Usage: snap watch [watch-OPTIONS]

Bonjour
Afin de vérifier tes liens, peux-tu donner le retour de

ls -ls | grep lrwx

Il me semble (sans certitude) que certaines applications snaps utilisent la référence au fichier .config/user-dirs.dirs
Sinon c'est l'artillerie lourde en faisant les liens en dur dans le fichier /etc/fstab

.

jeange · Le 07/05/2020, à 16:49

Désolé mais seulement de retour et sur 18.04.

Merci pour le man de snap pour 20.04, que je vais regarder.

De Gimp c'est impossible via home>lien vers image>puis l'image que je veux importer, la réponse est dans la capture du post précédent.

Évidemment : le snap de gimp est confiné, et tu continues à passer par ton gimp-confiné pour ouvrir un fichier qui est sur une partition autre que ton home : ça ne peut pas être différent de ta tentative précédente !

Je reformule :
0) le principe des snaps-avec-confinement, c'est de ne pas agir en-dehors du home.

1) tu fais une copie (plus sûre qu'un déplacement) momentanée de ton image dans ton home. Avec une appli non confinée (nautilus, ou

mkdir -v ~/temporaire

cp -av /DATA-WD500/.../mon-fichier.JPG  ~/temporaire

par exemple).

2) Alors, sur ~/temporaire/mon-fichier.JPG, tu peux lancer tes snaps confinés.

man snap de 20.04 a écrit :

--classic
       Put snap in classic mode and disable security confinement

Depuis 20.04, tu essaieras aussi :

snap --classic gimp

DE 18.04.4
Actuellement la 20.4 (déjà 3ème noyau) n'est qu'en phase de prise en main( pour moi) ainsi que Gimp 2.10.18, et j'ai fait la manip de copier des images (pas pour les travailler) dans le home pour les trouver avec Gimp et le truc qui me reste à faire est #88 mais avant cela je vais installer le scanner dès que serais en 20.04 et donner les retours.

DE 20.04

Après quelques modifications de Nautilus:

J'ai supprimé les copies de liens issues de 18.04 et via DT-WD500 ajouté des signets (partie inférieure) pour Documents Images Musique Teléchargements Vidéos, (Fich text et ORDI étant des signets classique issus de Documents)
J'ai enlevé (partie supérieure) Documents Images ETC.

Il est à noter qu'au niveau de Gimp cela ne change rien pour l'import d'image hormis les copier dans le homme.

@ geole ta commande ne retourne rien en 20.04 et pour le fun les voici en 18.04

jeange@jeange-W65-67SZ:~$ ls -ls | grep lrwx
  0 lrwxrwxrwx 1 jeange jeange     21 mars  12 21:42 Lien vers Documents -> /DATA-WD500/Documents
  0 lrwxrwxrwx 1 jeange jeange     18 janv. 17  2019 Lien vers Images -> /DATA-WD500/Images
  0 lrwxrwxrwx 1 jeange jeange     19 janv. 17  2019 Lien vers Musique -> /DATA-WD500/Musique

jeange@jeange-W65-67SZ:~$

et pour moko

jeange@CLV-W65:~$ snap --classic gimp
erreur : unknown flag `classic'
jeange@CLV-W65:~$

J'ai supprimé les copies de liens issues de 18.04

Pourquoi ???

jeange · Le 08/05/2020, à 20:33

DE 20.04

Pourquoi ???

Parce qu'après avoir installé le scanner avec un nouveau Bundle et en vérifiant l'installation dans Installés j'ai vu deux icônes de Gimp ! et clic droit sur une = dans Logiciels > 2.10.18-1 ubuntu-focal-universe, idem sur l'autre = dans Ubuntu software > Snapcraft illico désinstallé. Avec l'autre version aucun souci pour pêcher ce que je veux dans ma nouvelle version de Nautilus et en prime je peux lancer le scann depuis Fichier > Créer > Iscan sauf que ......................................... le scann ne veux pas démarrer, mébon ce sera un nouveau sujet de fil.
Pour me rassurer sur le scann je suis retourné en 18.04 pour t'offrir cela

jeange · Le 08/05/2020, à 20:33

salut Naziel

Nuliel · Le 08/05/2020, à 20:41

Salut jeange, c'est un problème de partitionnement de disque que tu as? (juste 4 pages de retard )

Non,
moko m'a aidé il y a une semaine pour modifier les partitions afin d'installer 20.4 à la place de 14.04 tout en gardant 18.04 et la partition de données de son côté; là je suis sur un problème d'install de scanner. Sinon RAS sur la 20.4.
