Hi All,

I am trying to install nova packages on the controller node. But I am facing a strange problem.

oslo.config.cfg.NoSuchGroupError: no such group: <oslo_config.cfg.OptGroup object

pip install oslo.config --upgrade I did but no change in error. Can you please help.

It looks like a problem with that package. Can you remove it, clean and update your repositories, and try the installation again?

If you can, enable the testing repository and install newer versions of software. That can get that problem solved.

Did anyone ever find a resolution to this issue? I'm also experiencing this problem. I manually re-installed all the Oslo packages with no success, followed by a manual re-install of all the Neutron packages.
