perl: warning: Setting locale failed. [Solved]

perl: warning: Setting locale failed.

perl: warning: Please check that your locale settings:

LANGUAGE = (unset),

LC_ALL = (unset),

LANG = "en_US.UTF-8"

are supported and installed on your system.

perl: warning: Falling back to the standard locale ("C").

Solved with just this command :

# locale-gen en_US en_US.UTF-8 hu_HU hu_HU.UTF-8

and then
# dpkg-reconfigure locales
