I have always been afraid to install Arch because they tell you it is difficult to install and unstable. I want a simple system following the KISS philosophy and install only what I need, which is little. I don’t need anything from the aur repository, for now. Just a year ago I installed Arch and there it is, no problems and doing every day pacman -Syu. It has been a real discovery for me, it’s the only distribution I’ve had this last year that hasn’t crashed. I didn’t expect it, but Arch has made me change my opinion and pay less attention to the opinions of “youtubers” and more to my own experience. In your experience of use, has Arch been stable in its operation?
I have had the same Arch install for years where Ubuntu on the other hand breaks after 2-3 major version upgrades from accumulated cruft.
It is important to keep Arch updated but sometimes I go a month or two without doing it.
Occasionally they have some update that’s not backwards compatible and you have to be a bit careful about it but if it breaks someone already has the answer on the forums from earlier that week. You can also install “informant” which displays the latest arch news post before installing because they usually warn you when there’s a breaking change.
