On newer distros like Xenial, Stretch, etc., we were incorrectly not installing the Python 3 version of the virtualenv package. This was accidentally working because most base images with Python already have this package too, but this was failing to install the right dependencies in our Docker builds, requiring unnecessary manual code. We fixed this some time ago for provision.py, but not for production.
