That happened to me few times, once GPU driver update, once grub update, both relatively easy to fix by searching the error on Endeavour forums and reading their official updates. And both of these issues was me not reading the update notes.

And when I was once forced to reinstall it was matter of an hour at most to have PC with working environment up and running, thanks to separate home mount and keeping all my installation notes in one place.

But one can do that with Ubuntu too.

I learnt one lesson from my manny distro-hopping sessions in the last 12 years, allways separate home from system amd keep all essential installation scripts and files in one place.

Just wait when you try AUR on arch systems. I was long time ubuntu based user but once I tasted rolling release and AUR I don’t want to go back.

I have just bought 8TB drive, but thus time I am using it ONLY to backup and store stale data, so far 1TB cleanes from my main SSDs. Wish me luck.
