I noticed this bug in queens/gate jobs for networking-odl too.

I added neutron as neutron-vpnaas has the same issue.

I don't think this is a bug in master neutron

The issue happens due to the confusion around zuul v3 migration.
The situation has changed since then according to the mailing list discussion.

python packages are installed based on requirements.txt of the project now, so appropriate dependencies of your project should be declared in requirements.txt in your project.
For example, neutron-vpnaas declares neutron 13.0.0.0b2 (rocky-2) [1].

Considering the above, there is nothing to do in the neutron side. I am marking this bug as Invalid (in neutron).

[Akihiro Motoki (amotoki)]

FYI: networking-midonet now uses zuulv3 docs job, so I believe the problem can be fixed by updating the 'neutron' line in requirements.txt to "neutron>=13.0.0" (rocky release).
