Linux

Fedora Workstation has been really good in my experience. The available software is shockingly up to date and I haven't run into much breakage of any kind in the year or so I've been using it across 2 systems (despite my best efforts every few months when the urge to tinker hits me). I do occasionally run into issues caused by the default SELinux policies, but they're not especially difficult to work around if you're comfortable using the terminal.

I do share your sentiment about the AUR - I definitely miss it at times. That said, Flatpaks and the fact that pre-built RPMs are so commonplace have both softened the blow a lot.

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.

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.

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".

Bazzite

My favorite distros are Gentoo and Debian.

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

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.

I've been using Linux for more than a decade and distro hopped quite a bit. Mint used to be my happy place, but recently within the last 5 years or so I've been on Arch derivatives. Endeavour was never stable enough for my liking, but Manjaro has been great. I did have to go back to a snapshot once, fairly recently, but that was primary because I fecked it up and not due to an update.

You mentioned that you have tried several Arch-based distros, so I'm not sure if this includes Manjaro.

Debian. I've had installations which went trough several major version upgrades, I've worked with 'set and forget' setups where someone originally installed Debian and I get my hands on it 3-5 years later to upgrade it and it just works. Sure, it might not be as fancy as some alternatives and some things may need manual tweaking here and there, but the thing just works and even on rare occasion something breaks you'll still have options to fix it assuming you're comfortable with plain old terminal.

Fedora. Ubuntu lost the crown.

If you want AUR specifically then you can only use Arch. That's the Arch package manager, and every distro has its own. Fedora has DNF, Debian/Ubuntu has apt...etc

OpenSUSE Leap is the way to go my dude. It's been formulated by pedantic Germans and you can't go wrong with YAST/zypper for package management.

I never wanted a hobby, but rather an operating system. I've been using Pop! for over six years. I only had one stretch where I felt like I was chasing annoying bugs and I don't remember it clearly enough to remember how long it lasted.

OpenSuse Leap or even Tumbleweed. After getting the media codecs up and running, and remembering to set you firewall zone to "home", you're pretty golden.

Could some of the instability issues you have on arch could come from what you are installing from AUR?

I use AUR for a few things and it is a great resource but the packages are maintained by users and can cause issues.

I update those packages carefully, remove them if I am no longer using them and reconsider which ones i actually need installed in the first place.

While doing this I have only had a handful of issues pop up while updating and usually there is a recent thread describing the issue and how to fix it after a quick search.

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.

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.

Garuda is about the same.

Arch base, preconfigured for btrfs snapshots on Pacman updates (and they provide a handy garuda-update wrapper to that), many niceties already done for you.

I've used the snapshot feature a couple times and only because the Nvidia drivers botched something horribly and I went back to the same snapshot a couple times.

And I use distrobox (rootless podman FTW) for some crap too. Like that time I needed WebEx at a moment's notice for a call (and they only provide a deb and rpm). Or spur of the moment dev environments when I don't wanna futz around with vscode devcontainers.

But with arch-based stuff, you gotta read the Pacman output. If you don't wanna, definitely reconsider immutable. Next time I can be bothered to reinstall, that's where I'm headed. Heck, you can start a distrobox with Arch and install all the AUR shit you please without a major worry.

Try blendOS. It's basically Arch but immutable. And SteamOS also exists.
