J'ai installé Ubuntu 12.04 sur un ordinateur. Tout va bien sans mise à jour. Juste après l'installation, il montrait environ 200 Mo de mises à jour à télécharger. Depuis lors, j'essaie d'installer toutes les mises à jour. Maintenant qu'il est partiellement terminé, certains logiciels (firefox, VLC) sont mis à jour. Il affiche toujours 39,3 Mo de mises à jour à télécharger et il échoue encore et encore. Chaque fois que j'essaie d'installer ces mises à jour de 39,3 Mo, cela montre qu'il ne peut pas se connecter à Internet, mais il n'y a pas de problème avec ma connexion (l'indicateur réseau montre qu'il est connecté et je peux parcourir et télécharger n'importe quoi). Cela me donne le message suivant:
Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch
Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch
Je pensais que c'était un problème avec la liste des sources. J'ai donc donné la commande suivante
sudo rm -vf /var/lib/apt/lists/partial/*
Auparavant, j'ai rencontré un type de problème similaire avec un autre ordinateur. À cette époque, cette solution a fonctionné pour moi, mais maintenant je suis toujours confronté à ce problème. N'importe qui, aidez-moi à résoudre ce problème.
Mise à jour
