That's actually just the initialization of variables at the beginning. shim-install fails because neither /boot/efi nor /boot/EFI exist as directory, which is weird. Can you confirm that? What's /etc/fstab, the output of findmnt and systemctl status /boot/efi (as root)? When YaST ran shim-install, /boot/efi was mounted and it finished successfully.
