[Bug 1466485] Re: keystone fails with: ArgsAlreadyParsedError: arguments already parsed: cannot register CLI option

 

Added neutron since it hits neutron jobs only.

One theory behind why it's neutron only is that if neutron is installed,
we can see that pip does some downgrade/upgrade dance at least for one
oslo library when installing neutron and neutron-*aas: oslo.middleware
is downgraded to 1.x, then upgraded to 2.x.

** Also affects: neutron

Title:
  keystone fails with: ArgsAlreadyParsedError: arguments already parsed:
  cannot register CLI option

Status in Grenade - OpenStack upgrade testing:
  In Progress
Status in OpenStack Identity (Keystone):
  Incomplete
Status in OpenStack Neutron (virtual network service):
  New

Bug description:
  Grenade jobs in master fail with the following scenario:

  - grenade.sh attempts to list glance images [1];
  - glance fails because keystone httpd returns 500 [2];
  - keystone fails because "ArgsAlreadyParsedError: arguments already parsed: cannot register CLI option" [3]

  Sean Dague says that it's because grenade does not upgrade keystone
  script, and the script should not even be installed in a way it's now
  installed (copied into /var/www/...).
