I'm having the same problem. Sometimes when I click unlock, nothing happens, and sometimes it gives me the error message about an unknown error occurring. I was already in the admin group, but I added myself to the polkitusers group and I'm still having the problem.
I'm not sure if it matters, but when I upgraded I had a lot of errors in dbus but it said it was OK because there was an upgrade in progress. Then the first boot had a lot of program crashes, but after that everything seemed fine. So perhaps this could be a dbus issue? -- Unlock button throws an error, doesn't authenticate https://bugs.launchpad.net/bugs/187335 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
