Comment 1 for bug 2007997

Traceback (most recent call last):

subprocess.CalledProcessError: Command '['juju', 'scp', '-m', 'foundation-openstack:admin/kubernetes-openstack', '/home/ubuntu/.local/share/juju/tmpkny3oqxm/netpolicy-test.yaml', 'kubernetes-control-plane/0:netpolicy-test.yaml']' returned non-zero exit status 1.

And the command output:

ERROR cannot connect to any address: [172.16.0.170:22]

This appears to be the same underlying issue as https://bugs.launchpad.net/bugs/2007708, in which juju scp commands fail when the kubernetes-control-plane units do not have floating IPs.
