python error during gbp-db-manage

[Larry Smith Jr.]

While attempting to install GBP on a fresh Ubuntu 14.04 install with Kilo and Neutron after following the install guide at https://wiki.openstack.org/wiki/GroupBasedPolicy/InstallUbuntu . I am presented with the following errors when running the below. Is this due to Juno vs. Kilo or something else? Obviously it is a python module that is causing this but what is the actual fix? If any?

gbp-db-manage --config-file /etc/neutron/neutron.conf upgrade head

Did you upgrade the GBP packages from Juno to Kilo? I ask because the Kilo code uses oslo libraries for logging [1] whereas this stack trace seems to suggest that you have Juno packages installed. The correct process would be to first upgrade the process and then try the DB migrate. Depending on which distro you are using, the package upgrade might also trigger a DB upgrade.

I have never had GBP installed. I was purely following the instructions
from the GBP Ubuntu install notes. Which I noticed were referencing Juno.

specifically the below method of installing... Nothing about Kilo
referenced.

0. Install Ubuntu 14.04 and OpenStack Juno
<http://docs.openstack.org/juno/install-guide/install/apt/content/>

1. Add the following line to /etc/apt/sources.list

 deb http://ppa.launchpad.net/group-based-policy-drivers/ppa/ubuntu utopic main

2. Install GBP packages

 sudo apt-get update
 sudo apt-get install group-based-policy group-based-policy-automation
group-based-policy-ui python-group-based-policy-client

3. To configure the GBP service plugin and drivers, edit
/etc/neutron/neutron.conf

3.1 Append "group_policy" and "servicechain" entry-point names to the
previously enabled service plugins:

  service_plugins = <already configured service plugins including l3,
lbaas, and fwaas>,group_policy,servicechain

3.2 Configure GBP policy and service-chain drivers

 [group_policy]
 policy_drivers = implicit_policy, resource_mapping

 [servicechain]
 servicechain_drivers = simplechain_driver

4. To configure GBP heat plugin, edit /etc/heat/heat.conf

  plugin_dirs=<existing heat
plugins>,/usr/lib/python2.7/dist-packages/gbpautomation/heat

5. Update GBP automation package name to work correctly with pbr

  sed -i 's/gbpautomation/group_based_policy_automation/g'
/usr/lib/python2.7/dist-packages/gbpautomation/__init__.py

6. Enable GBP UI on horizon dashboard

 ln -s /usr/lib/python2.7/dist-packages/gbpui/_*project*.py
/usr/share/openstack-dashboard/openstack_dashboard/enabled

7. Create GBP Database tables

 gbp-db-manage --config-file /etc/neutron/neutron.conf upgrade head
