I tried using `pip2` or `pip3` explicitly but it doesn't change the test results. I think the system python of the container has changed from Python2.7 to to Python3.5, probably from the updates to the xenial base image and/or the apt repositories.
This means all the python based tools like `tox` and `virtualenv` are now running in Python3.5, and the tests are assuming they run Python2.7. I don't know which of these tools causes the problem, but I would guess `virtualenv` since it is the `PythonVirtualenvOperator` that is failing.
