chroot, sarge and biarch

[Oliver Zimmermann <oz@bluemonk.de>]

Hi,

I am fooling around with my first 64 bit system in a sarge chroot and it
is time too ask a first dummy question to this forum.

I followed the recipe in the amd64-FAQ on
https://alioth.debian.org/docman/view.php/1314/21/debian-amd64-howto.html

The difference is, that I now have a chroot with 2.6.1 kernel and
sarge. In my understandig I need the "biarch toolkit" from
deb http://debian-amd64.alioth.debian.org/ sarge main
to compile my first 64-bit-kernel.

My problem is now, that I can't "apt-get install" the biarch toolkit
packages, because they are in the same version, as the installed
original sarge packages.

Is there an existing option in apt-get or dpkg, to force the reinstall
of the alioth-version over the original sarge packages? ...in other
words to replace libc6, libc6-dev, gcc-3.3, libncurses5-dev, wget and
bzip2 with the biarch versions?

In hope you can help,
Oliver
