I’ve been trying to deploy openstack using kolla-ansible method according to [this](https://kifarunix.com/deploy-all-in-one-openstack-with-kolla-ansible-on-ubuntu-18-04/) guide  
but when running:  
kolla-ansible -i all-in-one bootstrap-servers -vvv  
I get this error after completing few first Tasks:
