Yesterday, I have updated my Ubuntu 12.04 installation. After a restart, Ubuntu chose Chinese or some similar as default language. So, all my menus/windows are a mix of English and Chinese. Previously, I had the German language active.
I was able to re-order the language within the language-support. German is now my first option, followed by English and - maybe - Chinese. But now, my system is a mix of English (for the activity screen and the most programs like Firefox) and Germen (only for some the left panel of the gnome-tweak-tool).
All Settings >>
User Accounts I have selected
German for the language.
It seems, that Ubuntu ignores all my language settings - it's still in English. I have also tried, to re-install the language packs, but with no success.
Any suggestions, to bring my desktop back to the German language?
