When I run perl, I get the warning:
perl
perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset
If you are creating a rootfs using debootstrap you will need to generate the locales. You can do this by running:
# (optional) enable missing locales sudo nano /etc/locale.gen # then regenerate sudo locale-gen
