Hello Nico, I've seen that you have started packaging vtk 7.1 within the vtk6 tree, effectively targeting at replacing vtk 6.3. Please don't do this, we might have to package vtk-6.3 and vtk-7.1 in parallel (at least for some time). For further details see https://lists.debian.org/debian-science/2017/04/msg00009.html So just like we did with vtk6 vs. vtk5 at least I would prefer to package vtk7 in a separate repository. Many thanks, Gert
