The installation/Mongolian thing is completely unrelated. As regards the bogus language item in the list when you open Language Support, you can probably get rid of it by running this command:
sudo rmdir /usr/share/locale-langpack/mn And your locale() output looks fine. So nothing of that is an indication that your system is broken. As regards uninstalling the system: Well, it's up to you and how important you think that the ability to be able to export ibus-libpinyin user data is. Closing this bug, since the issue is not reproducible. ** Changed in: ibus-libpinyin (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893736 Title: ibus-libpinyin can not export user phrases To manage notifications about this bug go to: https://bugs.launchpad.net/ibus-libpinyin/+bug/1893736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
