I could probably summarize your experience as “skill issue”.

I don’t understand the hype of immutables, or usability even.

I suppose this article/blogpost by Lennart Poettering should suffice. Though, this article/blogpost by Colin Walters is also cool.

I tried Bazzite today after Nobara nuked itself, and I couldn’t even paste my old Firefox profile since the actual folder apparently sits within the immutable folder structure.

This is simply false as pointed out by others already.

I didn’t even have time to reach the software limitations with how fast I tried the next distro.

You will have a very hard time on Linux with that mindset. And, to be honest, literally any OS you aren’t already familiar with.

Still hopping though, because apparently Fedora just nukes itself when you try to install codecs

I wouldn’t be surprised if you just searched this through your favorite search engine and settled with whatever random solution you came across instead of relying upon RPM Fusion’s documentation on the matter.

and I think I have about every major distro tested by now.

While this could be true, I wonder what prevented you from sticking with any one of them.

Linux is cursed.

It’s definitely a lot harder if you’ve got major skill issues.

Been trying for days to install Private Internet Access’s client in a custom Bazzite image, but it’s slow-going to troubleshoot each failure to build, and I feel like I’m fighting GitHub more than the install script.

Have you contacted the Discord servers for Bazzite/uBlue and/or BlueBuild in hopes of resolving the issue?

They’re cool and very much willing to help out. They solved my issues a bunch of times with my own custom image. Perhaps, they are even capable of offering a solution to resolve the problem without requiring a custom image.

Wish ya good luck!
