It seems that urllib3 was update today.

Why does it even specify a maximum version? Does urllib3 make incompatible changes that often?

[reneeotten (Renee Otten)]

the incompatibility is due to py-requests and py-urllib3; the latter one was indeed recently upgraded and that version isn't compatible with py-requests yet. The issue was reported before, see ​Trac ticket 58382, and an attempt was made to resolve this in ​this commit. The latest update of py-urllib3 to 1.25.1 now doesn't work with py-requests anymore.

So I suppose a quick-fix would be to update the patches in py-requests for now. There is an open ​issue and ​PR upstream for py-requests that will address the incompatibility issue for real.
