Re: Environment variables "LANG*" and "LC_*"

Hello,

As far as I believe, there are some build processes that explicitly run 
under
en_US.utf8 for a variety of reasons.
Do you have this locale enabled in your /etc/locale.gen file?
Doing so and running locale-gen should satisfy these applications.

Best regards
