Public bug reported:
Installing the python3-pip package on 14.04LTS does not install all
required dependencies. python3-pyparsing is missing. Additionally, the
latest version of python3-pyparsing available in the 14.04LTS repos is
not compatible with the python3-pip version available. This means that
running update/upgrade on an LTS machine can result in not working pip3
in 2 different ways.
Installing and running python3-pip:

This looks related to an upstream bug in pyparsing 2.0.1 (but fixed in
2.0.2) combined with new pip or setuptools that require pyparsing. There
is some discussion upstream at
https://github.com/pypa/packaging/issues/91 .
