Freya security repositories turns to debian jessie

Question

I encounter various problems with my computer. The first is that my native language is French and I don't know how to make this the default language, so the login screen, keyboard and the session are in English, the keyboard is in UK format.

Second small thing, I get errors in updates, like what update-manager was unable to download information for certain deposits and in addition, under the "Update" tab it provides me up update for Debian Jessie (see screenshot).

Third thing is that it does not want to launch Software Manager with an error:

module = _import (distro_module_name, globals (), locals (), [], -1)

Thank you in advance for your answer. I have two other old cuckoos which perfectly rotate them. I do not know what goes with it.

Good late night;)

Answer 1

Click on "Applications" in the top-right corners and type "Language", this find the "Language & Region" settings. Open this and it will allow selecting French language in the left panel. This may require clicking "Unlock" in the top right (and entering your administrator or "sudo" password) or clicking an "install" button to complete installing missing languages. Hopefully once the system is configured in your language it will be easier to adjust update settings as you wish.

Rough Translation:

Cliquez sur "Applications" dans le coins en haut droite et tapez "Langue" , cette découverte les paramètres "Langue et Région". Ouvrez cela et il permettra la sélection de la langue française dans le panneau de gauche. Cela peut nécessiter en cliquant sur "Unlock" en haut à droite (et en entrant votre administrateur ou "sudo" mot de passe) ou en cliquant sur un bouton " installer " pour terminer l'installation de langues manquantes . Espérons une fois que le système est configuré dans votre langue , il sera plus facile de régler les paramètres de mise à jour que vous le souhaitez.
