I think it works as expected. If you run check-language-support without options, it lists uninstalled language support for all languages on the system, which approximately is the output of this command:
ls /usr/share/locale-langpack So if you have Russian as display language, and want to install Russian language support only, this command should do it: sudo apt install $(check-language-support -l ru) Please let me know if that explains it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910692 Title: check-language-support wants to install wrong locale packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/1910692/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
