Comment 18 for bug 639933

I see that this is marked as "Low" importance. I can't imagine why. After four hours of downloading files to go from lucid to maverick today, following the official upgrade path as described at www.kubuntu.org, everything ground to a halt with this error.

The lucid system, as recommended, was completely up to date, and had, to the best of my knowledge, only official lucid packages (i.e., no PPA packages). FWIW, it's a 64-bit system.
