How to fix a locale setting warning from Perl?

When I run perl, I get the warning:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset         


        

Answer 1

in my case, with debian8.6, i had to change settings in:

/etc/ssh/ssh_config for #AcceptEnv LANG LC_*

and sshd_config for #SendEnv LANG LC_*

then restart ssh service.

at last, did

locale-gen en_US.UTF-8 and dpkg-reconfigure locales
