Linux

Use distrobox brother, it is really underrated, I use it on my fedora PC so I can have access to the AUR all the time, you could even use Debian with it and have access the the AUR on a 2 year out of date install, seriously, it is really worth the effort of checking out, changed my Linux experience forever.

I would say fedora silverblue. Have been using it for a while. All updates, app and os, are distributed via app center so reasonably foolproof.

And a benefit is that it has podman out of the box so you can run docker images without fiddling with the terminal.

I put Fedora on a laptop as a whim almost 2 years ago.

My main computers are arch, but. I had an iso handy and hadn't used anything from based in years.

I am surprised at how quickly it gets updates. Gimp was at 3 before arch stable.

Anyways, I just keep updating the laptop and it just keeps working. I have yet to actually do anything for maintenance on it.

Look. I've been there. I started my Linux journey with Arch based distros, then distrohopped a lot, and finally found the best for me, and what I personally consider the best either for normal users or those that don't want to do any maintenance.

It's the Universal Blue family of distros: Bazzite (gaming / KDE / gnome) Aurora (standard / development / KDE) Bluefin (standard / development / gnome)

Set it and forget about it. It just freaking works. For GUI apps install from the Discover app store (which uses Flatpak), for cli apps use Homebrew (brew install whatever). If you can't find something, open Distrobox (already included) create an Arch container, install whatever you want from the AUR, and use it like you're used to. It works like freaking magic.

If somehow you manage to brick your installation, when you reboot you'll be able to boot to a past snapshot.

You just can't fail with this. It's the best of the best IMHO.

NIXOS, set and forget. It will not change unless you ask it to. Occasionally things might get renamed, but they set up warnings and don’t deprecate old naming for a long time

Wow, what a wall of text. I'm sorry but I'm sure I skimmed some parts.

Look. The bulk of the replies you're going to get will be like "this is my favourite distro and here's how it works for you" not "this is the best distro for your criteria." It's important to understand the deep level of bias you're going to get.

But your cause is a noble one. I use a particular style of distro because it can be trusted to install well, back out well, do both safely, and allow validation at every stage. I think it's a good candidate, and it's already been mentioned as a really great 'set it and forget it' distro.

Good luck.

First to answer your main question if I were you I would try NixOS, because it's declarative so it's essentially impossible to break, i.e. if it breaks for whatever reason a fresh reinstall will get you back to exactly where you were.

That being said, I know it's anecdotal but I have been using Arch for (holy crap) 15 years, and I've never experienced an update breaking my system. I find that most of the time people complain about Arch breaking with an update they're either not using Arch (but Manjaro, Endeavor, etc) and rely heavily on AUR which one should specifically not do, much less on Arch derivatives. The AUR is great, but there's a reason those packages are not on the main repos, don't use any system critical stuff from them and you should be golden. Also try to figure out why stuff broke when it did, you'll learn a lot about what you're doing wrong on your setup because most people would have just updated without any issues. Otherwise it really doesn't matter which distro you choose, mangling a distro with manual installations to the point where an upgrade breaks them can be done on most of them, and going for a fully immutable one will be very annoying if you're so interested in poking at the system.

Ive been a long term windows user. Almost 80% of my life. Tried macos and linux but always went to windows. Last year, i decided to move away from big tech in general. Ive moved away from most of it except windows, which is windows 10 LTSC. I tried ubuntu, kubuntu, fedora gnome, fedora kde, kde neon, arch (failed hard), arctix, endeavour and lastly i settled with linux mint cinnamon. A couple of tweak and a few hours. It feels like home. Goodbye windows, you will not be missed. I do dualboot windows 10 whenever i need to use program that only support windows.

Pls format your posts it's so much easier to read

I've been distro hopping for years. After each time trying a few distros, I always find myself coming back to Linux Mint (cinnamon desktop environment). It has everything I need, and just works beautifully out of the box. It might not be flashy or have the latest cutting edge features, but it's stable.

I'm currently running the Debian edition of Mint (LMDE), and wishing I was back on standard Mint. Nothing major, but a few minor persistent issues that never happened on Mint.

I did try NixOS (immutable OS), but it didn't seem to have support for all the apps I wanted. I gave up fairly quickly, so you'll probably have more success.

Bazzite

I've been wanting to try out NixOS for this very reason lately (although I don't break my system often). If everything works for me there, I'll switch to it.

I stopped using Arch a long time ago for this same reason. Either Fedora (or derivatives like Nobara) or an atomic/immutable distro (like Bazzite, Silverblue, Kinoite) is probably the way to go.

I used to feel like Ubuntu was a good option for this, but it no longer is: too often they try to push undesirable changes that need manual tweaking to fix after release upgrades. Debian Stable is generally good for low-maintenance use but doesn't keep up as well with newer hardware or newer updates to video drivers and mesa, which makes it suboptimal for typical gaming use. Debian Testing can be prone to break things in updates (in my experience, worse than Arch does).

I saw another comment recommend Rocky/RHEL, but note that their kernel doesn't support btrfs. Since you mentioned a root snapshot, I expect you probably use it.

You could try CachyOS, arch based and you can run it with KDE. I use Pop!OS and have been super happy with it

Look, this is the reason people pay RedHat money. Go install Rocky Linux, turn on all the automatic updates and ignore it for the next five years.

On the enthusiast side, NixOS seems to be working fine if you want newer versions of software or larger repos.

Mint. It's not sexy. But it always just works. Never had an update break anything. I've got an Nvidia card, which ppl said was notorious for not working with Linux, it just works. The installer just reached out and grabbed the appropriate drivers, so easy. Have yet to have a steam game not work.

10/10 would recommend for anyone.

I came from Arch to Fedora as well but using Universal Blue's images. In my case, Aurora (KDE), and daughter's Bluefin (Gnome). They update in the background and only install when you reboot. So far, most of the newer software releases such as web browsers or the desktop environment fall within a day or two for being installed which is a nice alternative. The big plus I see on these too is they are immutable so if something installs or breaks, you just boot into the previous version from Grub and go from there.

Additionally, OpenSuse MicroOS has options for whatever environment you are used to such as Gnome or KDE, this is immutable as well. I view all of these as "Set and Forget".

i'm trying out Aeon at the moment. it's from the opensuse people.

it auto-updates, it snapshots itself so any failed update will just silently revert, and it does flatpaks or distrobox only.

if you're okay with gnome, try it.

distrobox will give you access to the AUR and should be installable on any distro but the immutable/atomic approach might be worth looking into. I've been running bazzite on my personal machine and bluefin on my work machine for about a year now and it's been great. the only snag is learning the order of operations for installing things without a reboot.

I am just one data point but both distros have been rock solid for me and half the time I don't even realize updates had been run unless I see a new feature or something like that.

good luck on your journey!

Linux Mint. As an alternative: any kind of BSD is going to be pretty stable.

My favorite distros are Gentoo and Debian.

I can say with confidence that Linux Mint is what you're looking for.

ubuntu LTS is like this for me, but i can't recommend snaps. use it if you plan on uninstalling it and using flatpaks instead. i had a brief stint with mint and fedora and they seem good too.

in general, regardless of distro, i wait for the .1 releases after a big update, doing this has saved my ass before.
