Seems my response was a little too quick… I did find a solution, though I am not sure if this might break something in the future.
I uninstalled occt-misc:
sudo apt-get -y autoremove --purge occt-misc
and installed the specific version that was being called for:
sudo apt-get -y install occt-misc=7.6.3+dfsg1-7.1build1
which installed fine… then:
sudo apt -f install --install-recommends kicad --fix-broken
which installed KiCad 9!
Cant wait to see test out the new changes in KiCad 9!
