Just found out that there is actually support for .deb autoupdates through https://www.electron.build/electron-updater.class.debupdater, which isn't well documented on their main page (thought it was AppImage only). This could help install the few dependencies that are needed to run and make the overall linux experience better

Think .deb should be the first option to download on linux, with .AppImage the fallback for non debian based folks.

I was able to run the AppImage once I installed libfuse2, which did require adding the Universe repository. But I didn't need to install any of those other packages on a fresh Ubuntu 22 install. Not sure why you needed them and I didn't.
I updated the electron-builder.yml file to also output .deb files: #4554. I had a previous commit that added a deb.depends array that had those packages in there, but I removed it because it wasn't necessary for me to install the .deb file. I'd be happy to document installing libfuse2 if there is a place to do that. I didn't see anything that felt like a good place in the readme

The .deb file doesn't actually load in Ubuntu 24 for me, however. It seems it's getting killed by AppArmor. related: electron/electron#41066
