["abdelkader belahcene" <abelahcene@gmail.com>]

Hi,
When I try to install a package a receive the following  warning. I am
using the french language and the qwerty keyboard.


bela# dpkg-reconfigure locales
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
       LANGUAGE = (unset),
       LC_ALL = (unset),
       LANG = "fr_FR.UTF-8"
   are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Ne peut initialiser LC_ALL �� la locale par d��faut: Aucun
fichier ( means NO FILE FOUND) ou r��pertoire de ce type


where to change and fix the pb

thanks
bela
