sudo apt-get update
retourne quelques erreurs :
W : Failed to fetch http:// archive.ubuntu.com/ubuntu/dists/trusty/Release Impossible de trouver l'entrée attendue 'restricted/source/Sources' dans le fichier Release (entrée sources.list incorrecte ou fichier malformé)
W : Failed to fetch http:// archive.ubuntu.com/ubuntu/dists/trusty-security/main/binary-amd64/Packages Hash Sum mismatch

E : Le téléchargement de certains fichiers d'index a échoué. Ils ont été ignorés, ou les anciens ont été utilisés à la place.
cela semble se produire avec le dépôt officiel d'ubuntu. Une idée de la raison ?
Pour information, mon sources.list est le suivant :
