Reason for closing:  Won't fix
Additional comments about closing:  Might already be fixed with  FS#24292 , but otherwise no reproducible platform

Can you attach your pacman.conf please?

My pleasure. Many of the repos are commented out to make the --debug report smaller.

If it helps, this happened after my laptop battery fell out and my /var partition began to be mounted in /media/usbhd, and I couldn't boot. I fixed that by deleting that folder with the arch live cd.
   pacman.conf (2.2 KiB)

When you say "deleting that folder", what exact path are you referring to?

Can you post the above type output again but using --verbose as well?

Closing if I get no more feedback here in then next week or so.

Sorry for the delay.

I deleted /media/usbhd-1. This was where my /var partition was being mounted, incorrectly and randomly. The partition was reported as unmounted before I deleted that folder but apparently it was still mounted because I lost the whole cache, pacman log, everything. I had to install Arch again. I don't think this was a bug in pacman, just a unique case where random /var files got deleted.

This isn't even the first time something like this happens (unrelated to pacman):

There is a good chance this was the same as  FS#24292 , but I can't be certain. Once thing I do know is that we likely aren't going to make further progress here as the original system it was reproducible on no longer exists.
