This version fixes myriad segmentation faults in FreeCAD.

FreeCAD needs OCCT 7.9 to work, python3-occ is pinned to exact OCCT versions and doesn't support OCCT 7.9, wat do?
Looks like python3-occ is a library and not used by anything, and it's homepage is a little odd lel: http://pythonocc.org
It's also named incorrectly it seems, should probably be python3-occ-core

Try occt version 7.8.1, which is compatible with pythonocct 7.8.1.1, also update python3-occ to 7.8.1.1

Are you sure? It seems a bit strange to me that packages have to be held back because another that depends on it requires an exact version but is behind. The latest version of OCCT 7.9 has bugfixes which we want. python3-occ should either be always up to date or forward compatible with never versions of occt otherwise it doesn't fit with the kind of versioning system that's used here.

I would consider removing this python3-occ package unless there's some reason it's needed, just waiting for input from a maintainer.

umm you can remove python pkg
