I have a much easier time using REAPER rather than Ardour.

Nobara. But I’ve had them work on nobara before

Okular can digitally sign

Fitgirl installers just crash on me 🤷‍♂️

Commenting because I also am curious.

True, my bad

Okular, comes with Linux

In much the way I am aware of the Windows store: I avoid it and work to get the software directly from the source.

That is not the way things work on Linux - the repos essentially are the source. It is intended for apps to be packaged and distributed through official repos precisely to avoid the issues you listed, which are more often issues of downloading from sites. Package managers take care of incompatible versions and conflicts. That’s definitely a Windows bias my friend :P

80% of the reason to move to Linux is hating Windows, so yeah

I ask this with full sincerity - are you unaware of the package manager?

Bashing Ubuntu is getting really fucking old.
