RESOLU: Impossible d'upgrader 18.04.5 en 20.04

Bonjour,

J'ai une installation d'Ubuntu 18.04.5 dans une VM (VMware Fusion 8.5.10 sur iMac 27 avec OS/X Sierra) dont toutes les mises à jour ont été effectuées mais qui refuse l'upgrade à la version 20.04 poutant disponible.

Voici ce que je reçois comme réponses :

Please install all available updates for your release before upgrading.

Quelle commande dois-je alors utiliser pour forcer cet upgrade qui est bel et bien disponible alors que tous les paquets installés sont à jour (commande apt-get dist-upgrade)?.

Merci d'avance de vos conseils.
Cordialement et belle et bonne année 2021 à toutes et à tous.

Re : RESOLU: Impossible d'upgrader 18.04.5 en 20.04

C'est possible que tu aies des dépôts tiers qui posent problème et/ou des paquets orphelins. On va voir ça en détail :

cat /etc/apt/sources.list
ls /etc/apt/sources.list.d
cat /etc/apt/sources.list.d/*.list
apt list | grep "installé, local"
apt list | grep "installed,local"

Note que pour la dernière commande, je t'en donne deux variantes parce que j'ai l'impression que ton shell est en anglais. Dis-moi laquelle te donne un retour (s'il y en a un).

Re : RESOLU: Impossible d'upgrader 18.04.5 en 20.04

Moi ce qui m'interpelle c'est le choix des dépôts US mais bon... Je doute en effet que ma piste soit la bonne mais pour ma culture la question m'intéresse quand-même

Bonjour,

Vu :

Get:6 http://us.archive.ubuntu.com/ubuntu bionic-proposed InRelease [242 kB]

Pour info, la Doc : depots#proposed

Proposed
Les dépôts "proposed" contiennent des paquets proposés à fins de tests seulement ! Ils servent à tester des paquets ou des mises à jour avant qu'ils n'intègrent définitivement les dépôts principaux. Ils peuvent donc être à l'origine de plantage et de corruption de système ! N'ajoutez ces dépôts que si vous savez ce que vous faites !
Ces dépôts correspondent à la case à cocher "Mises à jour en préversion (proposed)" → onglet "Mises à jour" de l'application Logiciels & Mises à jour.

bonjour

sudo apt list --upgradable

On voit bien que le dist-upgrade ne ressort rien sur ses retours... Tu espères voir quoi de plus ? Et si le résultat était différent on ferait comment pour forcer une mise à jour si Apt ne voit rien...

Du coup j'aime bien l'idée de chercher du côté des packages verrouillés... Seulement sorti de synaptic (qui semble-t-il n'est plus conseillé car plus mis à jour) j'avoue ne pas savoir comment on s'y prend pour contrôler ce genre de choses...

Édit : @ xubu1957 > bof... Tu crois vraiment que ça pourrait en être la cause ? Je crois bien qu'il est actif chez moi et je n'ai pas eu de problème de cet ordre lors de ma migration... Après c'est sûr que je n'ai pas 56miles logiciels d'installé...

@Qid

N'ayant jamais installé de paquets proposed, pour les dégâts possibles sur un système et son impact sur une migration, je n'en sais rien du tout.

Re : RESOLU: Impossible d'upgrader 18.04.5 en 20.04

En tout cas, les paquets orphelins (sans dépôt) peuvent empêcher la mise à niveau. Et vu le bordel que contient Proposed, c'est fort possible qu'il y ait des paquets orphelins même avec le dépôt actif.

Pour ce qui est des dépôts US, il n'y a pas de raison qu'ils posent problème. Je ne sais pas si fnux a une raison particulière d'utiliser ceux-ci mais normalement, tous les miroirs sont mis à jour à peu près en même temps, le principal intérêt d'utiliser un dépôt plutôt qu'un autre c'est le temps d'accès et peut-être des restrictions chez certains FAI.

Ok... Si tu le dis et donc ? On fait comment la chasse aux orphelins pour leur donner une famille d'accueil ou les éradiquer (les pauvres ) ?

Re : RESOLU: Impossible d'upgrader 18.04.5 en 20.04

Avec ce que j'ai demandé en #2. La commande qui commence par apt list en l'occurrence mais les précédentes vont servir à vérifier les dépôts, sachant que certains dépôts tiers peuvent aussi poser problème lors d'une mise à niveau.

Bonjour,

Il y a toujours cette procédure pour rétrograder les paquets provenant des dépôts «proposed»:

Je ne sais pas si cela va parler. Mais ce qui sera sorti doit être supprimé puisqu'il ne peut pas être  mis à jour.

Désolé du retard à répondre mais j'ai eu un petit problème de santé m'ayant éloigné un bon moment de mon ordi.
Voici les réponses à tes questions:

Et voici la réponse à la question de geol:

fnux@fnux-linux:~$ sudo apt list --upgradable
Listing... Done

Merci d'avance de votre aide car j'aimerai bien upgrader cette VM au lieu de partir sur une clean instal.

PS: la raison des dépôts US est que j'installe systématiquement une version US mais juste avec un clavier AZERTY et que par défaut, ce sont alors ces dépôts qui sont choisis.

Tu as fait une faute de frappe dans la première commande ("ap" au lieu de "apt"). Je ne pense pas qu'il y ait de problèmes dans le fichier sources.list mais relance quand même la commande correcte pour en être sûrs.

Re : RESOLU: Impossible d'upgrader 18.04.5 en 20.04

Surtout pas de do-release-upgrade en l'état.

Tu as le dépôt Proposed dans ton sources.list. En règle générale, il ne faut pas l'utiliser : il peut être utile pour installer des versions des paquets en cours de test pour résoudre un problème spécifique, mais dans ce cas-là, on ajoute le dépôt, on met à jour uniquement le paquet concerné, puis on désactive le dépôt. L'avoir constamment activé, c'est le meilleur moyen d'avoir un système en vrac.

Donc, commence par éditer le sources.list :

sudo nano /etc/apt/sources.list

Supprime la dernière ligne, enregistre (ctrl + O, valide le nom de fichier avec entrée, ctrl + X pour fermer Nano), puis recharge la liste des dépôts :

sudo apt-get update

et redonne à nouveau le retour de la commande suivante :

apt list | grep "installé, local"

On va aussi vérifier si libpng12 est encore utilisé par d'autres paquets, vu qu'il n'est plus dans les dépôts (probablement un reste d'une version précédente, à moins que tu l'aies installé manuellement ?) :

sudo apt-get remove -s --purge libpng12-0 libpng12-dev

Puis on va passer aux noyaux :

Re : RESOLU: Impossible d'upgrader 18.04.5 en 20.04

A priori, tu peux virer libpng12 :

sudo apt-get remove --purge libpng12-0 libpng12-dev

et faire un peu de ménage derrière :

sudo apt-get autoremove --purge

Concernant les noyaux, tu peux supprimer ces vieux restes :

sudo apt-get remove --purge linux-image-3.13.0-32-generic linux-image-4.15.0-111-generic linux-image-4.15.0-60-generic linux-image-4.4.0-161-generic linux-image-extra-3.13.0-32-generic linux-image-unsigned-4.15.0-132-generic linux-modules-3.13.0-170-generic linux-modules-4.15.0-111-generic linux-modules-4.15.0-132-generic linux-modules-4.15.0-60-generic linux-modules-4.4.0-161-generic linux-modules-extra-4.15.0-111-generic linux-modules-extra-4.15.0-60-generic linux-modules-extra-4.4.0-161-generic

Ensuite, réinstalle ça :

sudo apt-get install --reinstall linux-generic

puis redonne à nouveau :

apt list | grep "installé, local"
