python – AttributeError: module ‘openstack.proxy’ has no attribute ‘Proxy’

I’m runing an Ussuri install on openSUSE 15.2. According the official install guide, the Keystone, Glance, and Placemente has run withou any bigger issues. But, when i try run any command with nova-manage, i have that message:

AttributeError: module ‘openstack.proxy’ has no attribute ‘Proxy’

That message occurs at every comand with “nova-manage”. Especially, i’m executing the step:

“Populate the nova-api database:”

from the official guide, the command is:

“su -s /bin/sh -c “nova-manage api_db sync” nova”

Every log has that error, even the journalctl -xe if try to start the service without populate database.

The others services runs fine.
The full log is:
