Fixed by https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=1469298

Updated python-urllib3 (1.26.2) broke with an older python-six. The urllib3 already had its copy of six removed in the previous build which caused the error.

Easy reproducer to show the underlying causes is to do the following:

$ python
import requests
requests.get(url="https://paste.centos.org/view/74829507")

With the broken package you get InvalidURL

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/requests/api.py", line 72, in get
    return request('get', url, params=params, **kwargs)
  File "/usr/lib/python2.7/site-packages/requests/api.py", line 58, in request
    return session.request(method=method, url=url, **kwargs)

    prep = self.prepare_request(req)

    hooks=merge_hooks(request.hooks, self.hooks),

    self.prepare_url(url, params)

    raise InvalidURL(*e.args)
requests.exceptions.InvalidURL: Failed to parse: https://paste.centos.org/view/74829507

Easy way to test this is to use ansible-operator image.

docker run -it --entrypoint=/bin/sh registry.redhat.io/openshift4/ose-ansible-operator:v4.5

Then run the reproducer python lines from comment #2

With the FIXED package you get a 200:
