Bug Description

Ubuntu 18.04, Openstack Train from the official repository.
Using ml2 driver with the provider networks.
Everything worked fine on the neutron 15.3.0, but after upgrade I got this:

Tried and reproduced on 5 different fresh installed servers.
Temporary workaround: moved to the 15.3.0 (copied files from older installation to the /usr/lib/python3/dist-packages/neutron).

As discussed above, there is known issue on upgrading from 15.3.0 to 15.3.2. It seems you were hitting that issue. However, based on discussion on https://bugs.launchpad.net/neutron/+bug/1903531, this issue won't be fixed.

Quoted from https://bugs.launchpad.net/neutron/+bug/1903531/comments/20

  Based on discussion with release and requirements teams on http://eavesdrop.openstack.org/irclogs/%23openstack-requirements/%23openstack-requirements.2020-11-24.log.html#t2020-11-24T21:36:35 it's the best to revert this patch now. I know it's very bad for people who already updated their envs but we can't do much more there :/ Sorry for that.
