I have this same problem in Ubuntu 12.04. When I installed 12.04 back in April 2012 it worked fine (as it has for the last several releases stretching back to 2006 when I first started installing multiple languages), but I re-installed 12.04 this past week and had this come up. I am trying to install the Korean, German and Spanish packs.
I tried sudo apt-get install -f. I tried sudo apt-get update && sudo apt-get dist-upgrade. I tried sudo dpkg --configure -a. I tried sudo dpkg-reconfigure locales. I looked in Synaptic under "status" and there are no broken packages or thorny issues. I tried installing each language separately instead of grouping them together. A thorough google/duckduckgo/ubuntu forums/launchpad search reveals that what I wrote above are the only offered solutions and none of them have worked for me. I wasn't sure if I had to file a new bug since the OP did his for 10.10 and my bug is in 12.04. If I need to file a new bug because of the different release, please let me know. ** Attachment added: "screenshot of the offending action" https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/632011/+attachment/3406920/+files/Screenshot%20from%202012-10-21%2015%3A24%3A17.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/632011 Title: gnome-language-selector won't install language support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/632011/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
