That's what you would need to get qgis installed, that I thought that
you were interested in.

It is not a bug, it's a consequence of the packages being involved in
transitions, and they are par of the course of development of Debian.
When all packages in the transition are rebuilt against the package
causing the transition, they will be installable again.

stable and testing are supposed to be free of that (althought the big
