Do you know how this can happen if they really use a 2 stage rsync?  I
understand that it can happen if I used an old packages file (and no,
I didn't immediately rerun apt-get update && apt-get -d upgrade to
reproduce it).  However it seems to me that, since the error refers to
the *new* .deb package file, that I really was using the new
Packages.gz file and that all the debs should have been in place.
Perhaps that's related to use of Package diff files?
