On my 2 Ubuntu 10.10 machines Update Manager works just fine, but on 2 of my
11.04 machines we got the pop up that updates were available for
installation by the Update Manager, but the update fails. I've been trying
on and off for the last 12 hours or so. Here's the results from the Update
Manager.
