warning: setlocale: LC_CTYPE: cannot change locale (UTF-8)

Do you get this error when trying to autocomplete a command using TAB on Ubuntu 10.04?

Here is a quick solution for getting rid of this:

Edit /etc/default/locale and add the following line:

LC_ALL=”en_GB.UTF-8″

If you don’t want to reboot the server, then issue the following command:

export LC_ALL=”en_GB.UTF-8″
