Tired of warning about locales in Ubuntu? Me too, and there is a fix.
You login, you try to compile something, etc. All the time you see this:
1 2 3 4 5 6 7 8 9 perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = "en_US:en", LC_ALL = (unset), LC_MESSAGES = "en_US.UTF-8", LANG = "en_US.UTF-8" are supported and installed on your system.
Edit the file
/etc/environment and add this:
1 2 LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
If it still fails, add the same lines to
