@thrasibule Thanks I rebuilt everything that was listed and it did the trick!

@txtsd did you rebuild python-xmldiff since you upgraded to python-3.9? all python aur packages need to be rebuilt after python upgrades. You can do something like pacman -Qo /usr/lib/python3.8/site-packages to know the list of packages that need to be rebuild.

I can't build python-fontmake right now because this package has requires python-unicode=12.0.0 and I have v13. Can you please relax that check to be greater-or-equal-to? It's probably too aggressive this way.
