Comment 2 for bug 1780376

This appears to be a problem with neutron-lbaas tox setup for stable/queens when running locally as outlined in [1].

As shown in recent lbaas stable/queens patches (running in zuul/gate) such as [2]; things run fine with zuul/gate and properly use neutron-lib 1.13.0 [3] and neutron stable/queens [4].

However if you run tox targets locally, neutron master is installed (not neutron stable/queens) and thus neutron-lib 1.16.0 (or whatever neutron master depends on) is pulled in. This is strictly a problem with neutron-lbaas tox setup for local targets [1].

That said I don't think anything is broken with neutron or neutron-lib, but rather the lbaas tox needs to be updated as per [1] for both master and queens branches.
