If you did that from root-shell, then most likely it DID work, but that was quite stupid thing to do because there are certain system-files which must be owned by root (or one of the other special user-accounts) for the system to work.

The reason for this most likely is that after you changed the ownerships, some of the files which "su" needs, now have wrong ownership, and so you can't use "su" anymore.

(As a test I changed the ownership of just two files: /bin/su and /usr/bin/sudo and after that "su" didn't work anymore, even if I got different error than you got)

Easiest way to fix this might be to reinstall Linux.

Other way would be to restore all file-ownerships and other things (like setgid/setuid bits) to how they were before you run the "chown -hR jathenry /" command.

Well, at least you now know that there are certain commands which are dangerous when used from root-shell.

There are some files for which you must not transfer the ownership for the system to work.

Why did you want to do that?
