OK, I think I might have found it. Looking through this <a href="http://ubuntuforums.org/showthread.php?t=613521&page=2">thread</a> it appears as though the local machine's entry in /etc/hosts is not quite right. My /etc/hosts was originally:
127.0.0.1 localhost 127.0.1.1 Udesktop.example.com And I changed it to: 127.0.0.1 localhost 127.0.0.1 Udesktop Udesktop.example.com After this change I killed and restarted Update Manager and it worked without problems. I'm guessing there should be a bug opened with Update Manager so that if the hosts name cannot be determined it will at least throw a dialog box up to complain. Hanging the system just because it cant resolve its own name is not a good thing. -- update manager hangs in hardy alpha 4 https://bugs.launchpad.net/bugs/188957 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
