Free and open-source.
Receives regular software and kernel updates.
Avoids X11.
The notable exception is Qubes, but the isolation issues which X11 typically has are avoided by virtualization. This isolation only applies to apps running in different qubes (virtual machines), apps running in the same qube are not protected from each other.
Supports full-disk encryption during installation.
Doesn’t freeze regular releases for more than 1 year.
We recommend against “Long Term Support” or “stable” distro releases for desktop usage.
Supports a wide variety of hardware.
Preference towards larger projects.
Edit: I’m new to linux
NixOS doesn’t have LTS releases, the regular releases every six months get replaced by the next release and support stops a month later. So you still have to update every few months.
Ubuntu LTS in contrast promises up to 10 years of support for old LTS releases.
