My Openstack clients stopped working

A quicky, possibly note to self. The other day I ran nova list and instead of getting a list of the instances in my lab I got:

Traceback (most recent call last):
  File "/usr/bin/nova", line 6, in <module>

    if six.PY2:
AttributeError: 'module' object has no attribute 'PY2'

A bit of DDGing did not reveal anyone else having this problem. A few Python developers had come accross it, but the fixes were not really relevant to me. The fix is quite simple though. Basically the Python Six module got corrupted somehow.

I am using Fedora 22, and which uses DNF as its package manager. This depends on Six, so I had to do a reinstall of the module:

sudo dnf reinstall python-six

Fixed! I have no idea what caused it to break as I do not really pay much attention on what is a fairly disposably workstation.
