This message tells you that "hostname" (i.e. what you see in output of command
"hostname") does not have A/AAAA record in DNS. It has nothing to do with PTR
records.

Message "Failed to update DNS records." is usually caused by misconfigured DNS
zones.

Please see
https://fedorahosted.org/bind-dyndb-ldap/wiki/BIND9/SyncPTR
for advice how to configure DNS zones to accept dynamic updates.

I hope this helps.
