The setup will ONLY continue if unbound_hosts are set

But after that, it runs and fails at the step: ... installing distro packages

This is because the /etc/resolv.conf points to the *not yet created* IP addresses.

So the whole process is totally stuck.

Could you paste your user config? The play should be skipped if no hosts match (no hosts are in the scope of the play).

culprit found.

instead of the usual way

git clone repo ; git checkout stable/ocata

this time, it was accidently

git clone repo ; git checkout -b stable/ocata
