Package: libvtk9-dev
Version: 9.3.0+dfsg1-4+b1
Severity: serious
Justification: violates Debian policy 5.6.34.3
User: debian-qa@lists.debian.org
Usertags: fileconflict

libvtk9-dev is declared Multi-Arch: same, but fails to coinstall.

The files
 * /usr/include/vtk-9.3/vtkcgns/src/cgnstypes.h
 * /usr/include/vtk-9.3/vtkEndian.h
 * /usr/include/vtk-9.3/vtkOptions.h
are shared by libvtk9-dev version 9.3.0+dfsg1-4+b1 as present in trixie
with varying content.

The files
 * /usr/include/vtk-9.5/vtkcgns/src/cgnstypes.h
 * /usr/include/vtk-9.5/vtkEndian.h
 * /usr/include/vtk-9.5/vtkOptions.h
 * /usr/include/vtk-9.5/vtkxdmf2/libsrc/XdmfConfig.h
are shared by libvtk9-dev version 9.5.2+dfsg4-3 as present in
forky|unstable with varying content.

Please ensure that shared files have bit-identical content across
architectures, move architecture-dependent files to
architecture-dependent paths or remove the Multi-Arch: same field.

Kind regards
