Not showing any proper output.

[saltdad64]

For several months now I have been using this script with no issues, up until switching distros (now running Pop!_OS 20.10), and now I'm getting output saying "Traceback (most recent call last):", instead of showing whether or not any music is playing.
So far I have installed the package python3-dbus, as well as python3 itself and rebooted to no avail. I also tried installing python-dbus, however the package does not seem to be available.
Something tells me that I must be missing some sort of package, and I can't help but worry I need that specific python-dbus package.
Any help would be greatly appreciated!

Try installing python-argparse
