I'm following the installation instructions at and all appears to go smoothly. Then at the Verify step, the command "placement-status upgrade check" throws the following exception:

$ placement-status upgrade check
Traceback (most recent call last):
  File "/usr/bin/placement-status", line 10, in <module>
  File "/usr/lib/python3/dist-packages/placement/cmd/", line 131, in main
    config(args=sys.argv[1:], project='placement')
  File "/usr/lib/python3/dist-packages/oslo_config/", line 2127, in __call__
  File "/usr/lib/python3/dist-packages/oslo_config/", line 2865, in _check_required_opts
    raise RequiredOptError(, group)
oslo_config.cfg.RequiredOptError: value required for option connection in group [placement_database]

I've scanned the [placement_database] section of placement.conf, and the only uncommented line is the 'connection' entry, which is exactly as specified in the installation documentation, except for my own password.

I am trying to upgrade from Queens on Ubuntu 16.0 to Stein on Ubuntu 18.04 and this is the first show-stopper I've encountered. Any help would be apprciated.

The command must be executed as root because the authority of /etc/placement is rwxr-x--- and other users do not have permission to enter the directory and so they can not find the placement.conf. This explains why:!/story/2006550 (!/s...)

Since you're doing an upgrade rather than a clean install you may need some different steps, have a look at:

The error you're getting suggests that the command may not be looking at the configuration file you think it is. You can make it explicit by passing a "--config-file PATH" argument placement-status

Thanks, I'll have a look at that. However, this was not an upgrade in the normal sense of the word. The command was in the Verify step of a new install. By "upgrade" I meant that I had set my Queens install aside and started afresh with Stein. I could have done better with my choice of wording...
