To be fair, I’m in the same situation. Fedora, Libsteam_api.so and more dependencies and all. Do want to share it out, even if I didn’t work for me. No idea if it is a case of “Source only” or if the devs don’t really know what they are doing and forgot to remove non-free dependencies like the Steam Integration.

Similarly, there’s System Admin Girl★まんがでわかるLinux シス管系女子 Imported a physical edition just for the quirky factor of a Linux Admin manga, but it is pretty well made and does explain pretty well some bits (even if from the first episode, they explain how to do VNC if i remember, from a Ubuntu 16.04 LTS desktop, so fairly easy and old) but it still on-going !

Here’s an actual FOSS cross-platform alternative with Windows, Mac and Linux (Need to be manually compiled and still experimental) https://screen-play.app/ https://gitlab.com/kelteseth/ScreenPlay
