I've found that this happens only when I connect to the Ubuntu machine using NX (with the "Desktop" setting set to Unix -> GNOME). If I log in locally or use the "Shadow" option of NX that connects to an existing console session, the unlock button works fine.
Through NX I get the same "Unable to look up session information for process" error when I launch network-admin from a terminal (I haven't tried users-admin) and have the "Unlock" button greyed out. Also, the /etc/hosts suggestions above didn't help me (although I tried them before trying to use network-admin locally, so it's possible that the hosts changes *and* logging in locally fixed it...). -- 'Unlock' button in admin utilities greyed out https://bugs.launchpad.net/bugs/231246 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
