neutron_plugin_create_nova_conf: command not found

I want to use networking-onos with the ocata branch of Openstack, since Mitaka is EOL.
I'm installing it using devstack.
In the compute node I have this error:

In my local.conf I'm enabling only n-cpu and neutron. No other log is saved under /opt/stack/logs

Maybe an update of networking-onos is needed.
