I’m using Arch Linux for 2 years. I subscribed to Arch’s mailing lists and I check my mails daily. I use flatpak instead of AUR.
I installed my system with archinstall and I update whenever I want. I didn’t have any issues yet and it’s the only distro that just works for me.
What about your experience? Any “breakage”?
I think this is what people mean with it being “unstable”. If you keep the system up to date, things will break at some point, and it’s up to you to sort that out. This is because Arch makes very different promises and tradeoffs than something like Debian. It’s a distro for those who want or need to customize or just like to tinker.
The reason I left Arch was because I carelessly installed a new major version of my WM which took me hours to get working. This made me realize that while learning how things work is fun, I want my OS to be a tool rather than a project.
(If you needed to reinstall Ubuntu every six months I guess you were already using it as if it was Arch ;D)
