While installing gpg-rsa, I got this and I am not quite sure what it is all about. I looked at the man page for 'locale' but I still don't know what to do. The only variable that I have set is LANG.
Setting up gpg-rsa (2.1.1) ... perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "en" are supported and installed on your system. -- Andrew
