[ubuntu-dev] Bug#717861: gdebi-core: gdebi mishandles the architecture-specific dependency qualifiers

[Francois Gouget]

Package: gdebi-core
Version: 0.9
Severity: normal

Dear Maintainer,

Here is how to reproduce this bug:
 * Download http://fgouget.free.fr/bugs/testdep.tar.bz2
   This is a small archive that contains a set of test, empty, Debian 
   package files along with their source.
   (run ./build to rebuild them)

 * Install the testdep-same_1.0-1_amd64.deb package.

 * Then run: gdebi testdep-same-arch_1.0-1_i386.deb

# gdebi testdep-same-arch_1.0-1_i386.deb

This package is uninstallable
Dependency is not satisfiable: testdep-same

Yet testdep-same-arch has 'testdep-same:amd64' as its sole dependency
so the installed amd64 testdep-same package should satisfy it. Running
dpkg confirms this:

# dpkg -i testdep-same-arch_1.0-1_i386.deb 
Selecting previously unselected package testdep-same-arch.
(Reading database ... 214863 files and directories currently installed.)
Unpacking testdep-same-arch (from testdep-same-arch_1.0-1_i386.deb) ...
Setting up testdep-same-arch (1.0-1) ...


gdebi-gtk and gdebi-kde exhibit the same problem.

Finally, note that support for this type of dependency qualifier has been
added in dpkg 1.16.5 (so before the Debian 7 release). For more details
see:

* Bug #676232: dpkg: Please add support for specific arch qualifiers (cross-dependencies)

  Add support for specific arch-qualified dependencies
    
  This allows to use dependencies with arch-qualified package names. For
  example:

    Depends: libc6:amd64 (>= 2.14), libgcc1
