This is what I get:
perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "en_US.utf8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C").
This is how I fix it:
export LANGUAGE=en_US.UTF-8 export LANG=en_US.UTF-8 export LC_ALL=en_US.UTF-8 locale-gen en_US.UTF-8 apt-get install locales dpkg-reconfigure locales
The export lines above can also be saved into either ~/.profile or ~/.bashrc.
