J'ai essayé d'exécuter les deux solutions recommandées, mais elles ne résolvent pas non plus le problème. J'ai essayé de rechercher le problème mais je n'ai pas pu trouver quelque chose de similaire.

Je suppose que votre liste de packages et de cache du gestionnaire de packages est obsolète.

mais pourquoi?

Vous utilisez xenial, l'un des packages que vous essayez d'atteindre libpam-systemd, que votre gestionnaire de pack essaie de récupérer à partir d'ici:

http://de.archive.ubuntu.com/ubuntu/pool/main/s/systemd/libpam-systemd_229-4ubuntu11_amd64.deb

Quel serveur vous répond avec un 404, cela signifie qu'il n'existe pas.

Si vous vérifiez le référentiel principal , vous verrez qu'il n'est pas là aussi.

Et si vous recherchez libpam-systemddans la xenial-updatessection des packages Ubuntu . le résultat serait 229-4ubuntu16 pendant que vous essayez d'atteindre 229-4ubuntu11, et l'autre chose est que cette nouvelle version est disponible sur le référentiel que vous avez choisi. le voici .

Que faire?

Mettez à jour vos listes:

sudo apt update

Il devrait faire le travail pour vous.

Cependant, si après la mise à jour des listes, vous rencontrez toujours le problème, essayez de supprimer ces fichiers, puis exécutez à nouveau la commande ci-dessus:

sudo rm /var/lib/apt/lists/*
sudo rm /var/cache/apt/*.bin
