Package: apt
Version: 1.0.9.6
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap
Consider a system with native architecture amd64 and foreign
architecture i386. Then consider the following empty packages
(generateable with equivs):
Package: foo
Architecture: all
Provides: bar:i386
Package: baz
Architecture: i386
Depends: bar
With dpkg, baz can be installed without complaint. Then, apt-get check
loudly complains that baz' dependency on bar is not satisfied.
The underlying problem is that libapt-pkg does not correctly parse these
provides. Internally, it creates a version named "baz:i386" with
architecture amd64. Of course, such a package name is invalid and thus
this version is completely inaccessible. Thus, this bug should not cause
apt to accept a broken situation as valid. Nevertheless, it prevents
using architecture qualified depends.
The attached patch fixes the parsing problem. After upgrading to a
patched apt and running apt-get --no-download update, apt-get check no
longer complains.
If the patch looks good, it would be useful (for rebootstrap) to have
this fixed in some suite (presumably experimental) soon.
