Hi Michael!

I am ashamed to say that I haven't made any progress on this. A lot of unexpected family and work events has prevented me from working on quite a few lingering issues with my open source projects especially this one as I don't have an Ubuntu machine anymore (not sure if doing it with Pop! will have any issues) and I also personally switched to Flatpak now that I have a quick way to fix the theme issue. I will still try to get an Ubuntu VM going the next chance I get and start catching up with maintaining the PPA though. Will keep you posted once I am able to make some progress.

Thanks for following up!
