The firewalld package prior to version 0.8.1-2 was missing the compiled
python modules. This has been fixed in 0.8.1-2, so the upgrade will need to
overwrite the untracked pyc files created. If you get errors like these
firewalld:
/usr/lib/python3.8/site-packages/firewall/__pycache__/__init__.cpython-38.pyc
exists in filesystem
firewalld:
/usr/lib/python3.8/site-packages/firewall/__pycache__/client.cpython-38.pyc
exists in filesystem
firewalld:
/usr/lib/python3.8/site-packages/firewall/__pycache__/dbus_utils.cpython-38.pyc
exists in filesystem
...many more...
when updating, use
pacman -Suy --overwrite /usr/lib/python3.8/site-packages/firewall/\*
to perform the upgrade.
