There's a problem in setuptools 24.0.0 (released today).

You can reproduce it just running on the shell easy_install:

# easy_install
Traceback (most recent call last):

Related fix proposed to branch: master
Review: https://review.openstack.org/336919

[Armando Migliaccio (armando-migliaccio)]

The Neutron functional and fullstack jobs are affected too.

[Henry Gessau (gessau)]

I proposed a requirements exclusion: https://review.openstack.org/336944

[Andreas Jaeger (jaegerandi)]

SEtuptools 24.0.1 was released to address this.

[Andreas Jaeger (jaegerandi)]

And our images have been updated, so this should be fine *now* - if not, please tell on #openstack-infra.

Change abandoned by Saverio Proto (<email address hidden>) on branch: master
Review: https://review.openstack.org/336919
Reason: fixed upstream in setuptools

[Mohammad Waseem Akhtar (gtalk-waseem)]

I am still seeing the issue. I am re-running ./stack.sh . But still facing following error

  File "/usr/lib/python2.7/UserDict.py", line 23, in __getitem__
    raise KeyError(key)
KeyError: 'processor_architecture'

It's mentioned above that SEtuptools 24.0.1 was released but it didn't get solved. May I know if I am missing here something.

FYI, I cloned devstack again and ran ./stack.sh

[Mohammad Waseem Akhtar (gtalk-waseem)]

After doing following update:

curl https://bootstrap.pypa.io/ez_setup.py -o - | python

Its working now.
