I'm not sure if this is the correct place to report it but I'm working on the Cinder Thirdparty CI requirement to move testing to Python 3.7. https://wiki.openstack.org/wiki/Cinder/3rdParty-drivers-py3-update https://wiki.openstack.org/wiki/Cinder/3rdParty-drivers-py3-update
Unfortunately this commit moving Kombu to 4.6.4 a day ago has broken the devstack setup scripts. https://opendev.org/openstack/requirements/commit/b236f0af43259959cb2a0f8288... https://opendev.org/openstack/requirements/commit/b236f0af43259959cb2a0f82880cebbdd0da7f27
It breaks because (I believe) Eventlet is monkey patching and kombu 4.6.4 interacts badly. See these two bug reports for more details.

Kombu 4.6.4 now results in this error when running

I'm open to any recommendation of a workaround. Downgrading to kombu 4.6.3 apparently works fine but I'm not sure how to do that within an automated devstack run.
Thanks
