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> from novaclient.shell import main File "/usr/lib/python2.7/site-packages/novaclient/shell.py", line 33, in <module> from oslo.utils import strutils File "/usr/lib/python2.7/site-packages/oslo/utils/strutils.py", line 26, in <module> from oslo.utils._i18n import _ File "/usr/lib/python2.7/site-packages/oslo/utils/_i18n.py", line 21, in <module> from oslo import i18n File "/usr/lib/python2.7/site-packages/oslo/i18n/__init__.py", line 13, in <module> from ._factory import * File "/usr/lib/python2.7/site-packages/oslo/i18n/_factory.py", line 26, in <module> from oslo.i18n import _message File "/usr/lib/python2.7/site-packages/oslo/i18n/_message.py", line 30, in <module> class Message(six.text_type): File "/usr/lib/python2.7/site-packages/oslo/i18n/_message.py", line 159, in Message 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.
