We want to upgrade our clients from 11.04 to 12.04 but with 12.04 apt-get tries to fetch 32bit sources from our mirror which just holds the amd64 packages. We have installed the testmachine with the 64bit alternate-CD and all our clients are 64bit. Why does it try to fetch from a 32bit-mirror?
Here some infos and output:

Forgot to mention that on 11.04 the problem hadn't exists as far as I can tell.
