I'm not sure why this doesn't work, as other parts of the code do the same. However, this is not what you want anyway: This check would already authenticate, i. e. you would get a password prompt right at the startup of l-s just for checking if you are an administrator. Instead, this should query polkit in "no interactivity" mode (no POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION), and check if it gets a "no but you can authorize" result (sorry, can't research the details here).
But with polkit we can probably just drop the whole is_admin check completely. If a non-admin user is starting l-s, the polkit dialog will still allow you to authenticate as another user who is an admin. -- 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: checks "admin" group membership instead of querying polkit Status in “language-selector” package in Ubuntu: Triaged 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.
