Note that python-configparser of what should be a suitable version is installed (and imports just fine manually): : luggage%; aptitude show python-configparser Package: python-configparser Version: 3.5.0b2-3 State: installed Automatically installed: yes Priority: optional Section: python Maintainer: Agustin Henze <t...@debian.org> Architecture: all Uncompressed Size: 412 k Depends: python:any (< 2.8), python:any (>= 2.7~), libjs-sphinxdoc (>= 1.0) Description: backport of the enhanced config parser introduced in Python 3.2 - PyPy The ancient ConfigParser module available in the standard library 2.x has seen a major update in Python 3.2. This is a backport of those changes so that they can be used directly in Python 2.7. This package contains Python 2.7 module.
