Foreman 2 - /etc/bind/zones.rfc1918:5 Error

foreman-installer is not working anymore. Foreman is installed but right now there are happening strange problem. I will now deinstall forman and try it again with a fresh installation.

Expected outcome:

Foreman and Proxy versions:
Foreman and Proxy plugin versions:
foreman_bootdisk 16.1.0
foreman_discovery 16.0.1
Distribution and version:
ubuntu bionic, foreman v2.0.0
Other relevant data:

Looks like an error with bind setup:

[ERROR 2020-05-13T08:05:54 main] Execution of '/usr/sbin/named-checkconf /etc/bind/named.conf20200513-6854-ryu2gv' returned 1: /etc/bind/zones.conf:1: zone '': already exists previous definition: /etc/bind/zones.rfc1918:5

Which version are you upgrading from? what parameters did you pass to the installer?
