It is an error with the hashsum. apt-get is geting a list with all hashes. If the hash in the list differs from the hash of the downloaded file, it won't be installed. That is very clever behavior. Most common for this issue are broken proxys or internet related filter.

If it was just a hickup, try sudo apt-get clean, which will clear /var/lib/apt/lists/* and than try sudo apt-get update, again. If this won't work, check your connection, if there is any device or service that is messing up with your connection.

In my case, switching from France server to principal server just solved the problem.

Translating from the names in French, I opened Software & Updates (Logiciels et mises à jour) and switched server in the select box Download from: (Télécharger depuis). You can open it from the "Activities" view or from a shell with software-properties-gtk.
