I installed my system using US English, but as my native tongue is Norwegian (Bokmål) I would like to use that on a daily basis on my system. More important, I want to use the Norwegian number formats.
However, in the language support settings, only Norwegian Nynorsk is available. I know there is Norwegian Bokmål support, as my home computer is installed with it. But it's not available from the "install/remove languages" dialog.
try this in a terminal:
this installs four packages. the latter two are only for the case you are using gnome. For KDE e.g. gnome should be replaced by kde.
After that you can hopefully select Bokmal language support.
