How to change the language of your Debian system
* First, you have to set EnvironmentVariables such as LANG, LANGUAGE, LC_CTYPE, LC_MESSAGES to your local language. Usually LANG (or LC_ALL) is sufficient. (shamelessly stolen from Claws Mail doc Check what you have at present with:
# env | grep LANG
* Second, you may also need to reconfigure your locales.
To do this, as root:
First: issue on a root terminal #export LANG=(the two letter code for your country).UTF-8 That is, for the Spanish language it would be:
# export LANG=es_ES.UTF-8
Second: reconfigure locales issuing the following command:
# dpkg-reconfigure locales
A window will ask you to select the languages (you select with SPACE) you want to have available. Choose your own.
Changes may not show immediately, a reboot will be needed.
