Hey, I recently discovered this problem too. It's probably a problem related to PolicyKit, indeed, and we can verify this very simply : the problem is solved by starting the software-center in the shell, via "sudo software-center".
I wanted to add two things to the discution : 1/ the solution proposed by quarkrad doesn't work on my computer ; 2/ the problem can be extended to all the other applications which require a call to PolicyKit Authentication Agent. For example, on my computer, I have exactly the same problem in the screen System > Administration > Users & Groups. None of the buttons work properly, for example "Advanced parameters" or "Add [a user]". -- Install Button not Working - nothing happens https://bugs.launchpad.net/bugs/591129 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
