This shows how bad things are in Linux land and how unfriendly Linux is for third-party apps. The idea that someone will package every application for every Linux distribution is delusional. The proper solution is to provide a standard API and make applications against this API. And of course there should be a sandbox for third-party apps.

Compare this to Windows where there is a standard API, standard set of pre-installed fonts and libraries, you download an exe and it "just works". However Windows has no sandbox and is not secure at all if you install any third-party apps. There are antiviruses, but they cannot guarantee detection of malicious code, and do not even try to block less malicious code like tracking and telemetry.

One might notice that there are Snap/Flatpak, however the issue with them is that the applications there mostly not work properly and have lot of bugs. Also they do not sandbox properly, for example, do not prevent reading serial numbers of equipment.
