I am updating to Ubuntu 18.04. I looked at this question, but that doesn't fix my problem. I have only EN showing, although I have 5 languages installed. I have only default regional settings but I cannot change any language settings, installed languages, or regional support. I think the update has messed up. How can I repair this?
sudo apt install --reinstall language-selector-*
locale
andlocale -a
output.sudo locale-gen
