This is a recent example of a problem that required manual intervention or the system would not boot after updates. This happens every now and then on arch, it’s why you should check arch news before updating.

For me it was that it said “forcing this upgrade may break your system, do you want to force the upgrade?”

And I was like “yeah, fuck it”, then installed mint after my system didn’t come back up (it was time for my annual re-install anyway)

No idea. I updated it, and then it wouldn’t boot. So, I reinstalled.
