Changing to the main servers allowed me to continue, but this isn't really a valid config change that should resolve the issue is it? I don't know what the cause of the problem is with the mirror servers, but if it can't be resolved, could there be a better error message (suggesting that the user change to main repos) when this happens during an upgrade?
I had the same issue when upgrading Intrepid -> Jaunty using the German servers:
W:Failed to fetch http:// de.archive. ubuntu. com/ubuntu/ dists/jaunty/ universe/ source/ Sources. bz2 Hash Sum mismatch
, E:Some index files failed to download, they have been ignored, or old ones used instead.
