[ALUG] peculiarities with debian apt and amd64

[Jenny Hopkins]

Hullo there,

I've been trying to set up a debian box with an amd64 processor.  Just
a standard install:  stable is fine.

I've taken the amd64 iso from here:
http://www.kmuto.jp/debian/d-i/    sarge-custom-0801.iso

I've edited my own apt sources list by hand and added these lines:

deb http://ftp.nl.debian.org/debian-amd64/debian/ stable main
deb-src http://ftp.nl.debian.org/debian-amd64/debian/ stable main
deb http://security.debian.org/ stable/updates main

apt complains that it can't find Packages.
/var/lib/apt/lists show Release and Sources but no Packages, and then
it shows security i386 Packages

(If I comment out the security line I get the same complaint about Packages)

cat /proc/cpuinfo knows all about the amd64ness of the box.

The odd thing is that this install is identical to the other amd64
box, nutmeg,  I have here: same iso, same sources list, and that is
happy:

nutmeg:/etc/apt# ls /var/lib/apt/lists/
ftp.nl.debian.org_debian-amd64_debian_dists_stable_main_binary-amd64_Packages
ftp.nl.debian.org_debian-amd64_debian_dists_stable_main_binary-amd64_Release
ftp.nl.debian.org_debian-amd64_debian_dists_stable_main_source_Release
ftp.nl.debian.org_debian-amd64_debian_dists_stable_main_source_Sources
lock
partial
security.debian.org_dists_stable_updates_main_binary-amd64_Packages
security.debian.org_dists_stable_updates_main_binary-amd64_Release

I've been round the install twice now and each time the same thing happens.

Puzzled,
Jenny
