With pleasure! Let me start by saying that I am a veteran of "our" AA ;-), I also get by technically with computers, which are a hobby of mine (necessary for work more and more often), with different hardware and OS software (win, nux and nix like), BUT I am NOT a developer (apart from some small bash sh ;-)). In any case, I follow various casts of various professionals in the sector to keep myself informed.
As regards the procedure I used and the platform on which I successfully installed 25assist and subsequently AA, it is this, in order (on quite ordinary hardware):
1) downloaded and installed fedora 42 workstation (kde gui)
2) for system optimizations, I followed some very exhaustive threads on github (I don't know if I can link to one in particular, I hope I'm not violating any rules, and it's this one
https://github.com/winterofhell/fedora-42-optimizations)
3) installed Steam for Linux (Proton and various runtimes) via rpm (Flatpak is the same but sandboxed so requires some permissions adjustments)
4) downloaded and installed 25assist AA
5) once the installation is complete, after logging in via 25assist, in the relevant control panel, INSTALL, install the Linux libraries.
This procedure, although slightly different in terms of optimizations, as they are already present, and installation of sandboxed packages via Flatpak, allows me to use successfully 25assist and AA also on fedora based platforms but customized and optimized for the game like Bazzite for example (or atomic versions of fedora like Kinoite).
I hope it is useful for other brothers in arms who by necessity have to use nux and want to have the opportunity to enter the world of old style AA ;-)
Oh, and THANK YOU from the bottom of my heart for the suggestion! I was so caught up in useless technicalities as solutions, that I didn't see the elephant in the room ;-))
Thanks again teddy
Have a good life and see you soon in AA
Ciao :-)
