Hi Andreas, thanks for taking care of QA, I always appreciate your bug reports.
libvtk9.1: missing Breaks+Replaces: libvtk9 (<< 9.1.0+really9.1.0)
While I agree that both packages conflict, I'm not sure if proposing a Breaks+Replaces is the proper solution here (and in general). Normally we want to have the library packages to be coinstallable and thus the packages only provide non conflicting files. Could you maybe adopt your template to mention that this hints to a problem in the package and propose to look into resolving the conflict as an alternative solution?
There are a lot of conflicting files: /usr/lib/<triplet>/vtk/hierarchy/VTK/vtk*.txt
These seem to dumps of the provided symbols. I did a quick test with pcl_viewer from the pcl-tools package and removing the hierarchy/ folder doesn't change the behaviour, So I assume we can drop the folder (or move it to the -dev package, maybe).

Package: libvtk9.1 Version: 9.1.0+really9.1.0+dfsg2-3~exp1 Severity: serious User: debian...@lists.debian.org Usertags: piuparts Hi, during a test with piuparts I noticed your package fails to upgrade from 'sid' to 'experimental'. It installed fine in 'sid', then the upgrade to 'experimental' fails because it tries to overwrite other packages files without declaring a Breaks+Replaces relation. This error may also be triggered by having a predecessor package from 'sid 'installed while installing the package from 'experimental'. See policy 7.6 at https://www.debian.org/doc/debian-policy/ch-relationships.html#overwriting-files-and-replacing-packages-replaces From the attached log (scroll to the bottom...): Preparing to unpack .../libvtk9.1_9.1.0+really9.1.0+dfsg2-3~exp1_amd64.deb ...
