Okay, like the title says, I tried everything I know and then some to change my system language to German, this included:
Language settings tool in the Control Center > Add/Remove Languages > remove all other languages except German and set default language to German etc.
Manually editing the language file in: /File System/etc/default/locale.
Opening Synaptic and manually removing all English language packages I could find.
Ruuning the following terminal command:
sudo locale-gen de_DE.UTF-8
sudo update-locale LANG=de_DE.UTF-8
(Edit: Added "sudo" to the above command as that is most likely why I got the "Permission denied" message!).
which returned a permission denied message:
despite the fact that the German language packs were/are already installed!.
Using "localepurge" to remove all language packages except German.
Does anyone have any ideas or is this a bug? as I have never come across this problem with an Ubuntu based system in the past. It just won't change even though all references to English were removed?.
The odd thing is, I was in the middle of writing a language guide and doing things I have already done a 1000 times in the past!. Needless to say, I haven't finished the guide yet!.
