tar: This does not look like a tar archive

[failpyre]

Script fails with error:
tar: This does not look like a tar archive
tar: Skipping to next header
tar: usr/bin/genfstab: Not found in archive
tar: Exiting with failure status due to previous errors
chmod: cannot access 'genfstab': No such file or directory
ERROR: Failed to locate genfstab. Aborting.

Error occurs on line 138: tar --transform='s,^([^/][^/]*/)+,,' -xf arch-install-scripts.tar.zst usr/bin/genfstab

Not sure if the file is bad? Mine is 14510 KB. I'm also lacking a /genfstab folder in /usr/bin.
