Thanks for the hints, Martin. I gave up on ls-dbus-backend, discovered gir1.2-polkit-1.0 and wrote a new function in utils.py. Now the code runs, but there is a tiny problem: AdminPrivileges() always returns True. :(

Even if the polkit dialog allows you to enter the credentials of an admin user, as long as you are a standard user you typically don't know any admin password, do you? Personally I think that the current UI, where the admin only controls are disabled (greyed out) for standard users, is better than letting the user know only by an authentication failure. Question is if there is a way to make polkit tell whether you can authenticate as the current _user_. Unfortunately the get_is_challenge() method seems to take into account the possibility to enter an admin password... -- 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.
