Configuration file given to multistrap

[Marcin Juszkiewicz (hrw)]

Problem exists because dpkg is told that i386 is foreign architecture which is allowed in system. APT follows it even if it should not.

[Torsten Spindler (tspindler)]

Does this problem still occur in Precise?

[Marcin Juszkiewicz (hrw)]

Yes, it still happens:

Status changed to 'Confirmed' because the bug affects multiple users.

[Svein Seldal (sveinse)]

I confirm the bug.

I didn't find this bug using multistrap, I rather used a custom script of my own which is attached here. It's purpose is to download a armel package and all its dependencies.

This script works when being run on a Natty amd64 and i386 host machine, while it fails on Precise amd64:

[Daniel Hartwig (wigs)]

From attached apt-wrap:

> mkdir -p $DIR/var/cache/apt/archives/partial
> cat >$DIR/etc/apt/apt.conf <<EOF
> APT::Architecture "$ARCH";
…

You should also add this line:

 APT::Architectures { "$ARCH"; };

which will prevent apt getting this list from "dpkg --print-foreign-architectures".

Alternatively, you could also try arch-restricting the generated sources:

 cat >$DIR/etc/apt/sources.list <<EOF
 deb [ arch=$ARCH ] http://ports.ubuntu.com/ubuntu-ports natty main universe

Similar changes should also be effective for multistrap.

[Svein Seldal (sveinse)]

Both approaches have been tested and confirmed. I'm going to stick with setting the APT::Architectures as I have less control of the real sources.list being used.
