I am following this guide: http://docs.openstack.org/project-install-guide/container-infrastructure-management/newton/install-ubuntu.html (http://docs.openstack.org/project-ins...) to install Magnum (Newton) in Ubuntu 16.04.

I have the following error when populating the magnum database:

# su -s /bin/sh -c "magnum-db-manage upgrade" magnum
      File "/usr/lib/python2.7/dist-packages/oslo_db/sqlalchemy/migration_cli/manager.py", line 47, in __init__
        raise ValueError('There must be at least one plugin active.')
    ValueError: There must be at least one plugin active.

Note: I had previously installed and removed the magnum packages. I had also manually removed the "magnum" database before re-installing the packages.

This is the same issue as in https://bugs.launchpad.net/magnum/+bug/1636131.

The fix for this was proposed in https://bugs.launchpad.net/ubuntu/+source/magnum/+bug/1632743 and the fixed python-magnum package has been uploaded as version 3.1.1-1 in the Debian Unstable repository (see https://packages.debian.org/unstable/main/python-magnum ).

I cannot see that Ubuntu has updated this package in their repos yet, however a temporary fix would be to download and install the Debian package from https://packages.debian.org/sid/all/python-magnum/download
