Package: freecad Version: 0.18.4+dfsg2-1 Followup-For: Bug #956516 It seems that as 0.18.4+dfsg2-1 is built against python3.7, and Debian now uses python3.8, that is the cause for the module import error.
This bug is preventing for example export of models from .stp into .obj, making Freecad unusable, because you cannot export your work anymore.
