Thanks for that clear exposition. I myself have had no problem with
these differences (assuming they could even be relevant). But can you
throw any light on why Pierre is apparently being served a .xz
compressed file by ftp.fr.debian.org which is making apt-get
(presumably expecting to receive a .gz file) fail to verify the
digest? (I can't even try reproducing this as I'm i386 and he's amd64.)

Cheers,
David.
