Hi again,
Another upgrade issue has been reported related to the gconf multiarch
split. This time, a known bug in the version of apt in Ubuntu 11.10 has
been seen causing gconf-service:i386 to be installed on an amd64 machine
together with gconf2:amd64:
https://bugs.launchpad.net/ubuntu/+source/gconf/+bug/962854
While apt should not have chosen the :i386 package when the :amd64 package
would have worked, the fact that the :i386 package satisfies the dependency
of gconf2 is a bug. This means that Multi-Arch: foreign is the wrong tag to
use for gconf2, which needs to be able to load the backend plugins contained
in gconf-service.
Per the multiarch spec, the intended label for a package such as
gconf-service that exposes both arch-dependent and arch-independent
interfaces is Multi-Arch: allowed. However, to take advantage of M-A:
allowed, packages would need to depend on gconf-service:any, which won't
work with the apt in squeeze. I've therefore uploaded the attached
workaround to Ubuntu, which further splits the package into a M-A: foreign
gconf-service, listed in the shlibs and used as the dependency for all
packages other than gconf2; and a M-A: none gconf-service-backend, containing
the actual files and used as the dependency of gconf2 and gconf-service.
>From the Ubuntu changelog:
* Split gconf-service further into gconf-service and gconf-service-backend,
one package being Multi-Arch: foreign and the other Multi-Arch: none, so
that we correctly handle the fact that gconf2 needs backend modules of
the same arch whereas other reverse-dependencies just need a working
daemon. LP: #962854.
This isn't pretty, but it's the best way to ensure clean upgrades from
pre-multiarch toolchains; so I think that's the best solution for Debian as
well.
