Bug#1013155: vmtk: vtk[6,7] removal

[gladk at debian.org]

Package: vmtk
Severity: important
User: gladk at debian.org
Usertags: vtk6_vtk7_removal

Dear maintainer,

Debian archive has now three major versions of the VTK (The
Visualization Toolkit) package: vtk6, vtk7 and vtk9. Old vesions
(vtk6 and vtk7) are not supported by upstream and the package itself
is not easy for the mainance.

We aim to drop old and deprecated version vtk6 and vtk7 packages
before the freeze of the Debian 12 Bookworm. The severity of this
ticket will be raised to serious some time for the freeze.

Your package depends on vtk6 or vtk7. Thus we ask you to migrate it
to the latest vtk9 package.

Thanks

Anton
