That’s not even just an issue for the user trying to install an app, but it also prevents developers for shipping on Linux. I think I saw that talk you mention. He was saying there was some app he wrote that he didn’t bother releasing on Linux, because it was too much work. Then took a dig at the guys who spent the time to get it there. If the guy who wrote the Linux kernel isn’t releasing his apps on Linux, something is very wrong. I don’t know how that didn’t lead to a major change.

Electron has been the biggest help for getting mainstream apps on Linux. Flatpak, etc help too… but all of those come with extra bloat to make it happen.

These have been solved problems on Windows and macOS for so long.
