I can reproduce the problem. I also tried to install Catalan, which ought to result in two additional language options: Catalan and Catalan- Valencia. However, only Catalan shows up in the list of selectable languages in gnome-control-center.
This makes me suspect that the problem is somehow related to the use of locale names with modifiers. $ locale -a | grep -E '^sr_RS|^ca_ES' ca_ES.utf8 ca_ES.utf8@valencia sr_RS sr_RS@latin sr_RS.utf8 sr_RS.utf8@latin gnome-control-center may not handle such locale names properly. As a workaround you can select Serbian using Language Support, i.e. the UI which shows up when you click the "Manage Installed Languages" button. (I don't think anyone can change the bug reporter easily. I subscribed your other name too to this bug report; that's sufficient for now, right?) ** Changed in: gnome-control-center (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1823778 Title: Unable to set Serbian as Language To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1823778/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
