Hi,
I'm resurecting this thread because I've just had an idetical issue and
after some searching found Andy's post below on the bitfolk lurker
archive.
I can't see any follow up posts so I just thought I'd let you know that
following Andy's suggestion to edit source.list seems to have fixed the
issue for me and I've now managed to run the upgrade.
So it looks like the problem was with the BitFolk's apt-cacher.
