Package: virtualenv
Version: 15.1.0+ds-1
If a network error occurs while installing a package with pip in a
virtual environment, a TypeError is raised when pip attempts to retry
the request. To cause this, I installed virtualenv and python and ran:
virtualenv venv
. ./venv/bin/activate
After this, we need to ensure a network error occurs. I did this by
turning off the internet connection on the machine entirely. Other
people have encountered this problem when their firewall was blocking
outbound traffic from pip. With my network disabled, I saw the following
behavior (running from within the Debian Stretch Docker image):

This problem does not occur if you reinstall the same version of pip
from PyPI by running pip install -I pip==9.0.1. I've also reproduced
this problem on Debian Unstable.

It works now. This is from a chroot running Debian Unstable:

I suspect this was related to a bug in python-pip related to pip not
supporting the way requests has been unbundled in Debian, which has been fixed,
so I'm closing the bug.
