I don't understand what kind of change is needed to address the above observations. The user who is created at a fresh 12.04 installation is initially included in the "sudo" Unix group, which gives him or her administrative privileges. If other users are made "administrators" via System Settings -> User Accounts (which tool should be used for the purpose), they are added to the "sudo" Unix group.
Since the "sudo" and "admin" Unix groups are included in 51-ubuntu- admin.conf by default, there is normally no need to edit that file. @Philipp: Which Unix groups are you included in? You can find out by opening a terminal window and run the "groups" command. ** Changed in: language-selector (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1008344 Title: [Precise] Language selector won't allow me to install languages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/1008344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
