Ubuntu has too many problems for me to want to run it. However, it has occurred to me that there aren’t a lot of distros that are like the Ubuntu LTS.
Basic requirements for a LTS:
- at least 2 years of support
- semi recent versions of applications like Chrome and Firefox (might consider flatpak)
- a stable experience that isn’t buggy
- fast security updates
Distros considered:
- Debian (stable)
- Rocky Linux
- openSUSE
- Cent OS stream
- Fedora
As far as I can tell none of the options listed are quite suitable. They are either to unstable or way to out of date. I like Rocky Linux but it doesn’t seem to be desktop focused as far as I can tell. I would use Debian but Debian doesn’t have the greatest security defaults. (No selinux profiles out of the box)
As suggested elsewhere, I think your requirements map quite well to Linux Mint. I prefer the Debian Edition but it has a shorter support window ( not LTS ).
If you want / need selinux then you may prefer the RHEL camp. Others have proposed Rocky. I would do Alma ( especially given your security focus ). Either way, the desktop software is going to be ancient and package selection limited. One solution is Flatpak. Another is distrobox.
An Alma desktop with applications coming from an Arch install via Distrobox would be the best of both worlds. The desktop and overall environment would be rock stable, secure, and boring. Yet the library of applications would be huge and, once installed, they would stay very up-to-date.”
SELinux is available on Debian though: https://reintech.io/blog/securing-debian-12-with-selinux
