 try: apt-cache show libc6-armel-cross:armel
 or as an alternative:
 apt-cache show libc6-armel-cross -o APT::Architecture=armel

That works. Didn't know apt already supported the :arch.

 And now for the really spooky part:
 Testing some more I find that the problem is the Replaces line. Changing
 libc6-armel-cross to Changing libc6-armel-cross2 makes libc6-armel-cross
 appear. Changing it back makes it disapear.

 This happens as APT adds Replaces against all known architectures to the
 package. So what you get above is correct as you have requested package
 libc6-armel-cross:i386 and this one is virtual as it is only created for the
 Replaces line. Still i guess it should do the same for virtual packages
 as it does it already if the package doesn't exist at all:
 Get the next possible match if no architecture is requested explicit…


 Best regards,

 David Kalnischkies

The odd behaviour makes sense now. But shouldn't it show the entries for
all architectures if no specific architecture is requested? Just like it
shows all versions if no version is specified.

Short of that it could say what it actualy searched for:

E: Can't select versions from package 'libc6-armel-cross:amd64' as it purely 
virtual
E: No packages found

E: Unable to locate package libfoo-armel-cross:amd64
E: No packages found

But showing the right thing would be better.

MfG
Goswin

Bug#590041: Mishandles Packages.gz from other archs

2010-07-23 Thread Goswin von Brederlow 
Package: apt
Version: 0.7.26~exp10
Severity: normal

Hi,

I have apt configured with Apt::Architectures = { amd64; armel; }
and a Apt::Post-Update hook that transforms the armel Packages.gz file
into something suitable for cross-compiling. But all packages that are
not Architecture: all are ignored from
ftp.de.debian.org_debian_dists_sid_main_binary-armel_Packages.
Replacing the amd64 Packages file with the armel one makes all
packages suddenly appear.

As a testcase I have stripped down the Packages files to bare minimum:

# ls -lh /var/lib/apt/lists/*Packages
-rw-r--r-- 1 root root0 Jul 23 06:51 
ftp.de.debian.org_debian_dists_sid_main_binary-amd64_Packages

# apt-cache show libc6-armel-cross
Package: libc6-armel-cross
Architecture: amd64
Version: 2.11.2-2~0.2
...


This is a big regression from previous experimental versions.

Description: Telepathy extension for Banshee
 This extension provides integration between the Empathy instant messenger and
 Banshee. It provides the following features:
 .
  * Download your friends' Banshee library metadata and check out what they
listen to, their ratings, BPM values, etc.
  * View your friends' playlists and export them to disk
  * Share what you're listening to with all your instant messaging friends by
advertising the track, artist, and album of the currently playing track in
Empathy's status message. This can be disabled.
  * Download your friends' music; one track at a time or a selection. You can
cancel ones in progress, queued, individually or all at once. The sender has
the option to cancel all in progress or queued transfers only. Both sender
and receiver get a progress bar. File sharing can be disabled.
  * Stream your friends' music. This feature can be disabled.
 .
 Banshee is a media management and playback application for the GNOME desktop.

More specifically: It ignores packages which are not arch :all or :armel
in this file. Your libc6-armel-cross package is :amd64.

Its done more or less on intension as files which have a specific
architecture (in this case armel) shouldn't include other architectures
by design. Could be changed, sure, but i am unsure if this should be done.
APT has done it that way since ever so far
(expect the experimental versions in which i broke it…).

(dpkg/status and flat Packages files are different, from these APT will
include all packages included in the Architectures list).

I thought that could be the problem. But that isn't it, or not just
that (see spooky part below).
