It was developed by the NSA and launched in 2000, officially adopted by the Linux kernel in 2003, and even today there are still distributions that do not use it or, failing that, the alternative, which is apparmor.

What's your personal Linux distro of choice for a regular desktop setup? My main uses are web browsing, light productivity (LibreOffice, GIMP), and Bitcoin software like Sparrow Wallet.
My daily distribution is Fedora Silverblue, but it's not for everyone, especially beginners, because you have to understand how it works.
The reason I use it is because it's unbreakable, and if it breaks, you can revert it in a second.
If you're not willing to use Fedora Silverblue, I'm more in favor of Ubuntu/Debian since I don't really like rpm distributions, but that's a personal preference.
Between Ubuntu and Debian, I would choose Ubuntu because it has newer software.
Thank you! Silverblue sounds interesting. I will definitely check this out.
Yes, I like Debian too. I believe last distro I used was Debian Buster I believe it was, with backports or flatpak apps.
