Configuring Locales

The Easy Way ;Install debconf (i.e. run apt-get update then apt-get install debconf, as root) ;Run dpkg-reconfigure locales as root

The Hard Way ;Edit /etc/locale.gen as root. If /etc/locale.gen does not exist, create it. An example /etc/locale.gen is below. ;Run /usr/sbin/locale-gen as root

A sample /etc/locale.gen

This file lists locales that you wish to have built. You can find a list
of valid supported locales at /usr/share/i18n/SUPPORTED. Other
combinations are possible, but may not be well tested. If you change
this file, you need to rerun locale-gen.

NOTE!!! If you change this file by hand, and want to continue
maintaining manually, remove the above line. Otherwise, use the command
“dpkg-reconfigure locales” to manipulate this file. You can manually
change this file without affecting the use of debconf, however, since it
does read in your changes.
