Go with one of the ready to use systems. Flatpak, Snap, AppImage. Snap is largely Ubuntu Ecosystem, Flatpak is independent. AppImage is an option if you do not need/want a Sandbox.

Great article. Reminds me of the time when I started using Linux as my main work system, back with kernel 0.99z

But then they would show the general public that Linux is a thing worth mentioning. I doubt that many people outside IT know about CBL Mariner.

I would start with Ardour and see if it fulfills your needs.

I always run occ upgrade and occ db:add-missing-indices after a package upgrade, just to be sure that I do not miss any database migrations. Using Archlinux I wrote a pacman hook so that it happens automatically.
