OMG thank you, thank you thank you. I’m trying to setup a new HASS mini-PC for my friend today, and after booting into Ubuntu live I couldn’t get Balena Etcher to run and I was losing my mind. Every forum post on the entire internet I could find about this, even ones from just a month or two ago, said you had to install libfuse2 on Ubuntu 22.04 to get .appimage files to execute, but I couldn’t get libfuse2 to install…thank you for saving me.
This reminded me of why I gave up on Linux years ago. The whole point of AppImage was to simplify app installation because installing software on Linux was often not user-friendly…AppImage is supposed to “just work”…and of course it doesn’t.
