Package: apt
Version: 0.8.15.9
Severity: normal

  Hi,

  I'm trying to use apt-get in a multiarch setup. I discovered that
"apt-get update" only download one foreign architecture. I suppose (see my
experience below) that the problem lies in the parsing of
"dpkg --print-foreign-architectures".

vdanjean@eyak:~$ /usr/bin/dpkg --print-foreign-architectures
armel
i386
mipsel
vdanjean@eyak:~$ cat /var/lib/dpkg/arch
amd64
armel
i386
mipsel
vdanjean@eyak:~$

If run "apt-get update" in this situation, only the (native) amd64 architecture
and the armel architecture are downloaded.

If I edit /var/lib/dpkg/arch to switch the armel and i386 architectures,
then "apt-get update" download amd64 and i386 architectures.

ie, "apt-get update" download the native architecture and the first foreign
architecture.

Now, if I change the output of "dpkg --print-foreign-architectures" to
output only one line:
vdanjean@eyak:~$ /usr/local/bin/dpkg --print-foreign-architectures
i386 armel mipsel
vdanjean@eyak:~$ cat /usr/local/bin/dpkg
#!/bin/sh


if [ "$1" = --print-foreign-architectures ]; then
	/usr/bin/dpkg "$@" | tr "\n" " " | sed -e 's/ $/\n/'
else
	exec /usr/bin/dpkg "$@"
fi

vdanjean@eyak:~$

Then, if I run "apt-get -o Dir::Bin::dpkg=/usr/local/bin/dpkg update", then
all four (amd64, i386, armel, and mipsel) architectures are downloaded.

  Regards,
    Vincent

Huh. Actually, a patch for this should be in 0.8.15.10 -
at least that is what the changelog in experimental claims.
But it's not in the debian-sid branch, only in my branch for sid.
/me unlocked the achievement: "screw version-control"
(goes and tries to fixes that…)

Conclusion: experimental versions have that already fixed,
next unstable version should fix that, too.


Best regards

P.S.: Are you sure your patch actually works?
fgets() will only return a single line.
My fix just does s/if/while/ in the fgets line.
