Comment 7 for bug 1029531

Thanks for the analysis of the log, I'll take a look at adding that Breaks.

I was using an up to date precise build, built 5 minutes before the test, so nothing in the archive should have been more recent that what was on the media, therefore the list I attached should still match what's missing from the media to make a clean successful upgrade. Any tweaks we do will just make a partial upgrade possible with a result quite different from what you'd get if you were online.
