Comment 2 for bug 1904041

I did some further digging and found that TripleO was pulling Neutron packages from master. I updated/synced to the latest development build ("current" RDO packages) of Victoria and now TripleO is using the correct packages. neutron-db-sync now works as expected. I cannot speak for the Kolla-Ansible side of the house but I suspect it may have been a similar problem.

Side note: TripleO used to use Kolla images but in Victoria and newer we have switched to our own containers to keep dependencies down and increase build time.
