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?
Arch was stable for me in the 5-6 years I used it (I’ve moved on to other distros since). The only issues I really had were grub and display related problems that were fixable in less than an hour. As another comment said, a quick search will instantly show you someone who already had the same issue and how it was resolved.
