Edit /etc/locale.gen using your favourite editor.

$ vim /etc/locale.gen

Comment out the following line:

xx_XX ISO-8859-1

*  where xx and XX are your languaje and region (e.g es_ES ISO-8859-1 for spanish from Spain)

Save the file and execute locale-gen to regenerate the locales with the lastest changes.

$ locale-gen

Reboot. You are done 😀
