Impossible d'installer le logiciel sur Ubuntu 12.10

Question

Je suis novice avec Ubuntu. J'essaie de télécharger le lecteur de pdf Okular à partir du Software Center, mais je reçois une erreur. Au début, il demandait l’installation de paquets provenant de sources non authentifiées. Lorsque je clique sur , utilisez cette source .

mise à jour du cache enter image description here

Puis après un certain temps, il me montre cette erreur: enter image description here

J'ai lu cette question "Nécessite l'installation de paquetages non fiables?" et j'ai essayé de reconstruire le cache comme indiqué dans la première réponse en utilisant:

Sudo apt-get clean cd /var/lib/apt Sudo mv lists lists.old Sudo mkdir -p lists/partial Sudo apt-get clean Sudo apt-get update

et obtenu cette sortie:

They have been ignored, or old ones used instead.

Ensuite, j'ai essayé de réinstaller Okular, mais j'ai de nouveau les mêmes erreurs. J'ai essayé de changer la source du logiciel sur le serveur principal et j'ai également activé l'authentification pour les sources de logiciels tiers, mais aucun progrès n'a encore été accompli.

Ubuntu 12.10 n’est plus supporté plus depuis mai 2014. Vous devez soit mettre à jour vers une version plus récente d’Ubuntu (c'est-à-dire 14.04), soit trouver un autre référentiel. Le dépôt alternatif pour 12.10 est publié ici (merci @ rubo77 pour l'avoir trouvé). Plus d'informations sur la mise à niveau peuvent être trouvées ici .

sbergeron · Answer

Comme 12.10 est EOL, les mises en pension ont été déplacées. Effectuez une mise à niveau vers une version plus récente d'ubuntu (ou rétrogradez vers la version 12.04, bien que cela ne soit vraiment pas recommandé) pour accéder aux mises en pension normales. Si vous devez absolument utiliser cette version d’ubuntu, envisagez d’ajouter les dépôts d’archive et google pour savoir comment le faire. En fin de compte, ma réponse est la mise à niveau vers 14.04, elle est plus stable et supportée.
