Comment 2 for bug 1864399

My impression is that we have two bugs here as I am found this today: https://review.rdoproject.org/zuul/build/de8f3d0c42254e65b42ab964346ff3f0/console

```

:stderr: DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

```

As you can see the list over versions does not contain any newer version.

I am confident that our mirroring is broken in my case.
