Actually, I've been seeing the problem too.  It looked like a bad
interaction between approx and cdn.debian.net mirrors (and
http.us.debian.org too, since it's a load-balanced mirror, which
means, individual files can be fetched from different server).
Retrying 'apt-get update' several times inside chroot seemed to
succeed sometimes.

instead of 
	apt-get update
doing
	apt-get update -o Acquire::PDiffs=false

seems to help, since it's failing in getting the correct diff index
for Sources file, but it's just making things less flakey.
