I tested this morning and looks like it is fixed as Juju is reporting the node as active now:

MACHINE  STATE    DNS            INS-ID         SERIES  AZ

8        started  fe80::1        juju-a64e14-8  xenial  

But they have a IPV6 IP address and that gives errors:

jenkins@lmic-s9-instance:~/kubernetes$ juju ssh 3
ssh: connect to host fe80::1 port 22: Invalid argument

It's not clear to me either how that's affecting the charms although most of them come up, but there are some errors and I'm not clear now whether they're related to this:
