[Bug 1130419] [NEW] apt resolver doesn't do sensible things when satisfying a cross-dependency on a virtual package (steam, wine)

Public bug reported:
As a result of the LTS enablement work in 12.04.2, we now have a
situation where for the first time, a library dependency of a
substantial number of packages in main is satisfied by two different
real packages (libgl1-mesa-glx-lts-quantal Provides: libgl1-mesa-glx),
and there isn't one right "default" answer to the question of which
package should be installed (users who installed 12.04 have one option;
users who installed 12.04.2 have a different one).
This interacts quite badly with apt's resolver when cross-installing a
multiarch-capable package that also has a dependency on one of these
libraries. For example, the steam:i386 package has the following
dependencies:
Depends: libc6, libgl1-mesa-dri, libgl1-mesa-glx, xterm | gnome-
terminal, zenity
Since libgl1-mesa-dri and libgl1-mesa-glx are both real packages, apt
tries to pull these in by name. However, the libgl1-mesa-glx-lts-
quantal:amd64 and libgl1-mesa-dri-lts-quantal:amd64 packages already
installed have a Conflicts/Provides on libgl1-mesa-glx and libgl1-mesa-
dri respectively, and the conflicts relationship crosses architectures.
It's reported that when installing via software-center, this conflict
may even result in removal of the X server. I can't reproduce this
myself (since steam64 has now been withdrawn from the software center
until the problem can be addressed), but apt is certainly not able to
find a solution to this problem on its own:
sudo apt-get -o Debug::pkgProblemResolver=1 install steam

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:

Since we don't have enough information to say with certainty that all
Conflicts from packages of a different architecture can be ignored, it
seems we need apt's resolver to be smarter, and possibly give priority
to implementors of virtual packages that are already installed for a
different architecture when trying to satisfy dependencies.

Bug description:
As a result of the LTS enablement work in 12.04.2, we now have a
situation where for the first time, a library dependency of a
substantial number of packages in main is satisfied by two different
real packages (libgl1-mesa-glx-lts-quantal Provides: libgl1-mesa-glx),
and there isn't one right "default" answer to the question of which

This interacts quite badly with apt's resolver when cross-installing a
multiarch-capable package that also has a dependency on one of these

dependencies:
Depends: libc6, libgl1-mesa-dri, libgl1-mesa-glx, xterm | gnome-
terminal, zenity
Since libgl1-mesa-dri and libgl1-mesa-glx are both real packages, apt
tries to pull these in by name. However, the libgl1-mesa-glx-lts-
quantal:amd64 and libgl1-mesa-dri-lts-quantal:amd64 packages already
installed have a Conflicts/Provides on libgl1-mesa-glx and libgl1
-mesa-dri respectively, and the conflicts relationship crosses
architectures.
It's reported that when installing via software-center, this conflict
may even result in removal of the X server. I can't reproduce this
myself (since steam64 has now been withdrawn from the software center
until the problem can be addressed), but apt is certainly not able to

Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
steam:i386 : Depends: libgl1-mesa-dri:i386
Depends: libgl1-mesa-glx:i386
E: Unable to correct problems, you have held broken packages.
Getting a correct result requires the following:
$ sudo apt-get install libgl1-mesa-dri-lts-quantal:i386 libglapi-mesa-
lts-quantal:i386 libgl1-mesa-glx-lts-quantal:i386 steam
Since we don't have enough information to say with certainty that all
Conflicts from packages of a different architecture can be ignored, it
seems we need apt's resolver to be smarter, and possibly give priority
to implementors of virtual packages that are already installed for a
different architecture when trying to satisfy dependencies.
