First example is the pep8 job, which was passing a couple of days ago but now fails with:

ERROR: Could not find a version that satisfies the requirement gitdb2===4.0.1 (from -c /home/zuul/src/opendev.org/openstack/requirements/upper-constraints.txt (line 776)) (from versions: 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6, 3.0.0, 3.0.1, 3.0.2, 3.0.3, 3.0.3.post1, 4.0.2)
