Erreur 'apt-get update'
Je reçois constamment une erreur et un avertissement sur la sortie de apt-get update d'hier soir sur mon PC Ubuntu 14.04 64 bits.
La partie significative de la sortie de la commande apt-get update est la suivante:
Get:1 http://security.ubuntu.com trusty-security InRelease [64.4 kB]
...
W: Failed to fetch http://in.archive.ubuntu.com/ubuntu/dists/trusty/Release
Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file)
E: Some index files failed to download. They have been ignored, or old ones used instead.
Le contenu de /etc/apt/sources.list est également le suivant:
#deb cdrom:[Ubuntu 14.04 LTS _Trusty Tahr_ - Release AMD64 (20140417)]/ trusty main restricted

J'ai expérimenté avec le fichier sources.list hier et après quelque temps, j'ai réinstallé Ubuntu vers 14.04. Même après la réinstallation, je vois cette erreur.
Toute aide est appréciée. Merci d'avance.

Après avoir désélectionné Mises à jour non prises en charge , onglet Mises à jour dans software-properties-gtk, le 1er avertissement a été supprimé. Alors maintenant, je ne reçois que les avertissements et erreurs suivants:
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file)
E: Some index files failed to download. They have been ignored, or old ones used instead.

Comme suggéré par Raphael (voir les commentaires), changer le serveur de téléchargement dans Logiciels et mises à jour en Meilleur serveur résout le problème.
L'erreur peut être due à des erreurs de serveur. Changer le serveur a tendance à résoudre le problème. Pour ce faire, allez:
Software & Updates > Server > Other
puis sélectionnez le meilleur serveur
