It fails because you do not have DNS set correctly. The machine you are
joining is not sending its correct hostname.

You cannot miss out one item in the checklist and then expect anything
after that to work.

Try the dns checklist:

That's on Debian. When that doesn't work, try putting only the hostname
in /etc/hostname.

Go no further if the join throws errors.
