A similar bug: https://bugs.launchpad.net/neutron/+bug/1903531
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. ** Changed in: neutron Status: New => Won't Fix -- You received this bug notification because you are a member of Yahoo!
