Impossible d'installer 7Zip dans Ubuntu 13.10

Lorsque j'essaie d'installer 7Zip dans le Centre logiciel Ubuntu, il indique qu'il est disponible à partir du référentiel Univers. Je clique sur "Utiliser cette source", je m'authentifie et rien ne se passe.

C'est le cas pour tout ce que j'essaie d'installer, bien que ma connexion Internet soit correcte.

Et quand j'exécute la commande Sudo apt-get update, j'obtiens les résultats suivants:

Ign private-ppa.launchpad.net saucy InRelease 
Err archive.ubuntu.com saucy InRelease 
Err archive.ubuntu.com saucy Release.gpg Could not resolve 'hostname'

Exécutez les commandes suivantes pour installer 7Zip:

Sudo apt-get install p7Zip-full p7Zip-rar

Pour référence future, vous devriez apprendre à utiliser apt-cache search pour trouver des candidats à l'installation. Par exemple, 'apt-cache search 7Zip' renverra une liste de paquets connus de votre système pour faire référence à cet utilitaire.
