The oslo.config version that came with my Ubuntu was 1.2.1, which had this same error. Check it with:
root@controller:~# pip search oslo.config oslo.config - Oslo Configuration API INSTALLED: 1.2.1 LATEST: 1.4.0.0a5
So, what I did was to update it with:
pip --upgrade oslo.config
Then, check:
root@controller:~# pip search oslo.config oslo.config - Oslo Configuration API INSTALLED: 1.3.0 LATEST: 1.4.0.0a5
And with this, the command finally succeeded in its execution. Hope this helps!
