Thank you for opening this bug and helping make Ubuntu better. Unfortunately, you have not provided any real data on what might have happened, so the only answer I can give you right now is "I have no idea". I also have temporarily assigned the 'update-manager' as the package (but I really do not know yet).
Please open a terminal and run 'sudo apport-collect 657636' -- you will be asked to provide your password so that the command may be executed as the superuser. This will collect basic update logs into this bug, and help us try to figure it out. ** Package changed: ubuntu => update-manager (Ubuntu) ** Changed in: update-manager (Ubuntu) Importance: Undecided => Low ** Changed in: update-manager (Ubuntu) Status: New => Incomplete -- Not able to shut down https://bugs.launchpad.net/bugs/657636 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
