Failed to find luks partition

…perhaps an improperly merged .pacnew file - saw this mentioned at the Arch forum, but the question and thread was from last year and it wasn’t made very obvious that this was the reason

suggestion: look at the contents of /etc/mkinitcpio.conf - the encrypt HOOK

I don’t know whether you did try to

  • chroot:
  • check that file’s contents
  • rebuild the initrd: mkinitcpio -P linux
  • update-grub
  • exit
  • reboot

Please provide commands and their output as well for every step
so we can see what you see and did and the immediate results of it.
