These days, there is also the official guided installer for arch that may be worth a try. I had similar issues with Manjaro, but since this has been around I've never had a reason to try any arch derivative.

My brother had that OS. It worked fine until it got a bug that the computer froze when he enabled the wifi, and the only way to stop it was pressing the power button. I couldn't figure out the cause, and there was many unnecessary things coming with the OS, so I helped him to install Arch instead. Now, it works well and feels clean.

EDIT: based on the comments, the issue happened with arch too.

If they want a full-fledged system running Arch, then EndeavourOS might be the best bet. Archinstall is great for quickly installing Arch but there's still quite a lot of set-up required after that, and for some people, they don't really want to do that. EndeavourOS is essentially a ready-made Arch set up (or as another person said here, a very opinionated Arch install), and is based on Arch's repos but has its own extra repo for its own software while Manjaro holds the packages back for two weeks (which creates sync problems with, say, the AUR)

there's also Endeavour which I'm pretty sure uses the Arch repos

It feels like a fork for the sake of "I use arch BTW"

It doesn't add anything of value on top of "vanilla" arch, but they still manage to break stuff that works in Arch, occasionally ddos AUR and if I recall correctly there was some controversy because the developers were assholes

Going to weigh in, manjaro devs are kinda incompetent. They've ddosed the aur twice in the exact same way, showing that they hadn't done anything to solve the inherent issue. Their ssl certs keep expiring, even though auto-renewal takes about ten minutes to set up while telling their users to "change your clocks time" as a patch solution while they fix their certs once (which took hours).

Their head arm developer sent a patch to asahi linux which broke x-org, showing he shipped code without so much as running the thing to test making a change well known and documented to cause this error with zero benefit to the project or his commit. This, after manjaro claimed that "manjaro works on the macbook m1" by using the asahi kernal with a full on campaign, shipping a random kernel from the release page which was known to be broken. It would not turn on, and could easily have broken users systems. Asahi at the time simply did not work, nor would it for a while.

They keep making dumb mistakes learning nothing and not asking for help when it's obviously needed. Their two week delay, though it fixes some issues, commonly still ships known broken updates when unnecessary.

They put the aur directly next to flatpack and snap in pamac without a proper warning. The aur is dangerous, you need to know how to use it, and to read the pkgbuild. Anybody can put any app up there and you'll be running arbitrary code on the system. Flatpack and snaps are quite safe, the aur is not. A while ago, a guy put a list of people who can "fuck themselves", insults, and homophobic statements alongside two calls to a IP grabber in the dolphin emulator package. When there's malware on linux, the aur is likely to be the first targeted

They've made many suggestions in their forums that lead to bad habits, putting more stress on arch devs and their servers.

It's due to the continual incompetence of the devs, them damaging other projects they depend on, and the devs being quite unfriendly in the forums that people hate manjaro. I'd love to see it become better as the concept is a decent one but with the current leadership and work being done I have to caution against it's use

My problem with Manjaro was that they continually kept their repos behind arch while still depending on the aur and other arch infrastructure. This caused problems like aur packages not being buildable, and software that used the arch debuginfod server being unusable.

Read the screenshot by OP. Can confirm that, too

Mostly due to how the team behind Manjaro acts. Personally have been using plain arch for years while my Manjaro installation fucked itself after half a year.

Don't understand why you're being downvoted, this is definitely the cleanest solution.
There's also a new handy app to manage the containers of distrobox: BoxBuddy, I've just noticed it switched to Rust and GTK now and, even better, it's right there on Flathub!

Not to contradict your experience. More for my own understanding. Do you use the AUR much?

Why use an Arch-based distro if you can't use the AUR? It's like one of the most, if not the most defining feature of them

AUR is also not supported on Arch, so support has nothing to do with it.
