Ububtu does not come with support for the Norwegian locales by default. Here is how to add it:
sudo apt-get install --reinstall language-pack-nn
sudo apt-get install --reinstall language-pack-nb
Add the following to: /var/lib/locales/supported.d/local:
nb_NO.UTF-8 UTF-8
nn_NO.UTF-8 UTF-8
Regenerate locale files:
sudo dpkg-reconfigure locales
To see the list of locales that exists, use:
locale -a
