Impossible de mettre à jour le logiciel - les paquets / fichiers indel non approuvés n'ont pas pu être téléchargés

Question

Lorsque j'essaie de mettre à jour via Software Updater, cette erreur s'affiche:

Bien sûr, on devrait normalement résoudre ce problème avec (comme je l'ai déjà demandé à propos de ici ):

Sudo apt-get update && Sudo apt-get upgrade

Cependant, cela produit simplement ses propres erreurs:

E: Some index files failed to download. They have been ignored, or old ones used instead.

Je pensais que cela pourrait être lié à une sorte de problème de connectivité, mais j'obtiens la même erreur, que mon VPN fonctionne ou non ... Sans parler du fait que tout le reste n'a aucun problème de connectivité.

Toute aide serait appréciée...

À propos, voici le terminal complet:

http://au.archive.ubuntu.com est en panne et pour une raison farfelue fonctionne sur un serveur redhat :)

Passez à un autre miroir pour le moment ou réessayez plus tard.

Recherchez "logiciel" dans votre tiret et cliquez sur Logiciel et mises à jour .
Cliquez sur le menu déroulant pour Télécharger depuis et sélectionnez autre .
Ensuite, cliquez sur sélectionnez le meilleur serveur pour sélectionner automatiquement le meilleur serveur ou vous pouvez simplement cliquer sur serveur principal à la place, mais ce ne sera probablement pas aussi rapide.

Vous pouvez essayer ceci:

enter the terminal and type this: Sudo bash gedit /etc/atp/sources.list

puis faites ceci

put ## in front of src http://au.archive.ubuntu.com etc..

et vous pourriez mettre à jour à nouveau, et cela pourrait bien fonctionner de cette façon.
