and the third has stated they will not implement age attestation methods.

Do you have a source l, I went looking earlier and couldn’t find anything

If I were to take a guess, it is because it requires you to do software installation via CLI. If you are looking for a distro with a software store, I would say fedora or lmde is the move

I can’t help you there, I don’t personally use cachy I am just making assumptions based upon what I have heard and how it works on other distros

Packages != kernel, so probably not. I don’t know how power usery you want to be, if fine with some tinkering then staying with arch makes sense and as I said in the prior post I recommend endeavoros. If you want no tinkering, kubuntu is fine I would just lookup snaps and see what you are getting yourself into, and if that turns you away I would recommend mint lmde.

Some quick googling tells me that their optimized packages require 12th gen or newer, so that is likely what was messing you up. here is the link I found if you are interested, but I think your hardware is just to old.

I don’t know how old your hardware is, but iirc cachyos’s kernel specifically doesn’t support older hardware, so it could be that it is just too old. If I were you I would try out endeavoros if you can deal with a little more technical package management or you could use the base arch kernel on cachy. Of course your switch to kubuntu should continue to work assuming it was a kernel issue, I just don’t like canonicals vision.

Iirc manjaro changes the package management to not be rolling release, I think you would have to add back in the base arch repos and risk versioning issues.

I don’t know what a x-kiosk is, that might work, in any case if someone is on gnome or KDE, any solutions that rely on x11 will be deprecated in 2 & 3 major versions respectively

That is operating under the assumption that you aren’t using Wayland, as far as I could determine after a few hours of tinkering the only way to get a remote desktop to work under Wayland is by using an app that queries the xdg portal since Wayland’s harden permissions will stop xwayland based remote desktop solutions.

I use rustdesk over LAN for my remote desktop which has been rather stable and quick, although I don’t know the exact protocol that it uses, so if rdp is necessary I wouldn’t know of that is satisfactory for op’s needs.
