[résolu] CUPS, localhost:631 impossible à atteindre

Bonjour,

Le problème est résumé dans le titre.
Vu autrement : tout fonctionnait... j'avais accès à toutes mes imprimantes. Et, aujourd'hui, je m'aperçois que je ne peux plus lancer mes impressions.

Quelques infos...

« sudo service cups restart » réponds

cups stop/waiting

puis le terminal est bloqué, il me faut faire CTRL+C

« sudo /etc/init.d/cups restart »

 * Restarting Common Unix Printing System cupsd
cupsd: Child exited with status 1
                               [fail]

« cat  /var/log/cups/error_log » ne réponds rien, le fichier est vide... et il est daté du 28/06 !!!

« cat /etc/cups/cupsd.conf »

Description: Common UNIX Printing System(tm) - PPD/driver support, web interface
 The Common UNIX Printing System (or CUPS(tm)) is a printing system and
 general replacement for lpd and the like.  It supports the Internet
 Printing Protocol (IPP), and has its own filtering driver model for
 handling various document types.
 .
 This package provides the parts of CUPS which are needed for using printer
 drivers.

Pour info, ces derniers temps, j'ai essayé (en vain) d'utiliser docker et des conteneurs... Je ne sais absolument pas si mes manips ont pu causer le désordre côté CUPS

Edit du 11/07/16 : docker fonctionne parfaitement...

Re : [résolu] CUPS, localhost:631 impossible à atteindre

La commande « system-config-printer » m'ouvre cette fenêtre (à la place de la liste de mes imprimantes)

Puis, je clique sur « Se connecter » et... j'obtiens

Erreur du serveur CUPS
Une erreur s'est produite lors de l'opération CUPS : « failed to connect to server ».

Mes imprimantes, sont bien là...
« ls /etc/cups/ppd »

Re : [résolu] CUPS, localhost:631 impossible à atteindre

Bjr,

Bonne nouvelle : problème résolu...
Méthode : j'ai récupéré sur une ancienne configuration mon répertoire /etc/cups
Origine du problème : inconnu !
