 All of the failed lines represent symlinks to other files that do exist on
 disk.

 I also note that these failures aren't actually reported unless I redirect
 the output and without that redirect, there's no indication that anything
 has failed. I'm not sure if that indicates the file is actually detected
 (unlikely) or if that's a different issue where the failures aren't
 reported.
