Comment 6 for bug 1865832

hmmm still seeing this a bit on stable/rocky e.g. there https://review.opendev.org/#/c/710314/
but looks to be back green now in zuul builds
https://zuul.opendev.org/t/openstack/builds?job_name=tox-py35&project=openstack%2Ftripleo-heat-templates&branch=stable%2Frocky&job_name=openstack-tox-lower-constraints

not sure yet if we still need to move off py35 as per http://lists.openstack.org/pipermail/openstack-discuss/2020-March/012942.html
