Hi all

I am following the instruction of official openstack doc in order to install Neutron. When I am trying to populate the Neutron databases which is already created, the following message is show. the command and output is echoed into the paste of Openstack which is as follow: http://paste.openstack.org/show/781094/

The output of /etc/neutron/neutron.conf http://paste.openstack.org/show/781095/

the output of ML2 file: http://paste.openstack.org/show/781096/

Here are the document that I have followed: https://docs.openstack.org/neutron/stein/install/controller-install-ubuntu.html (https://docs.openstack.org/neutron/st...) https://docs.openstack.org/neutron/stein/install/controller-install-option2-ubuntu.html (https://docs.openstack.org/neutron/st...)

the summary of the error is as follow: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/oslo_config/types.py", line 844, in __call__ value = self.ip_address(value) File "/usr/lib/python3/dist-packages/oslo_config/types.py", line 730, in __call__ self.version_checker(value) File "/usr/lib/python3/dist-packages/oslo_config/types.py", line 750, in _check_both_versions raise ValueError("%s is not IPv4 or IPv6 address" % address)
