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 Desktop Packages, which is subscribed to language-selector in Ubuntu. https://bugs.launchpad.net/bugs/1008344 Title: [Precise] Language selector won't allow me to install languages Status in “language-selector” package in Ubuntu: Incomplete Bug description: In a new install of Ubuntu Precise, I cannot make any system-wide changes in the language selector (such as installing languages or clicking "Apply System-Wide"), only user-specific changes. All those controls for system-wide changes are greyed out, although my user does have sudo abilities and I would be able to enter the root password of the machine. The machine is freshly installed, but with customizations specific to our site, e.g. ldap authentication for users. Specifically, my user is an ldap user, not a local one, and there is a group in the ldap directory which was granted sudo capability by adding it to /etc/sudoers. My user is part of that group. sudo on the command line and gksudo work fine.
