Comment 4 for bug 1819672

  I have the same problem while trying to upgrade from Rocky to Stein (openstack overcloud update prepare). Is there a workaround until the bug is fixed? It's being open since March...

  One of the solution I know is to run "openstack overcloud plan delete overcloud", which would help when overcloud is not deployed yet. But, the plan can't be deleted if there is a deployed overcloud and one wants to upgrade it. Can the plan be fixed somehow?

```
openstack overcloud update prepare --templates \
-e ~/vxrdo/templates/node-info.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/disable-telemetry.yaml \
-n ~/vxrdo/templates/network_data.yaml \
-e ~/vxrdo/templates/network-isolation.yaml \
-e ~/vxrdo/templates/scheduler_hints_env.yaml \
-e ~/vxrdo/templates/network-environment.yaml \
-e ~/vxrdo/templates/ips-from-pool-all.yaml \
-e ~/vxrdo/templates/ceph-ansible.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/docker-ha.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/services/octavia.yaml \
-e ~/vxrdo/templates/firstboot/firstboot.yaml \
--ntp-server 10.35.10.2 \
-e ~/vxrdo/templates/init-repo.yaml \
-e ~/vxrdo/templates/containers-prepare-parameter.yaml \
 2>&1 | tee prepare.log
```
