y default there are 3 keyboard languages installed. Icelandic, Swedish and US. When trying to add a new language (Norwegian) or remove some of the others, it works. But as soon as rebooting, all these changes are lost. This is when using the keyboard handler by right-clicking on the flag icon at the top of the screen.
I have also tried to make changes using the Menu > Preferences > Keyboard an Mouse, and those changes seem to survive a reboot, but after the reboot the flag on the top is always changed to Iceland and the keyboard as well.
I did try to make changes using raspi-config, but there is an error message after changing the locale settings "There was an error running option I1 change locale"
How can I make the changes to norwegian permanent?
