Comment 4 for bug 626798

Update Manager just crashed when trying to update Ubuntu 11.04. I have just upgraded my computer from an Ubuntu 10.10 install. Apt-get in terminal is working fine.

This is the error it gave: "update-manager crashed with DBusException in _run(): org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

I am sure that the network connection wasn't broken.
