I'd want to hear from others on this matter, as my experience with
repairing upgrades is limited.
I recommend you don't take any action on the following immediately, until
others have weighed in.
John figured that the error you've got could be related to having
containers in the environment.
Unfortunately it appears that the upgrade step doesn't work if there are
any containers, as it
mistakenly thinks they're MAAS machines (and is rightly told that they
don't exist in MAAS). It'd
be great to get confirmation that you do have containers in your
environment.
Now, this could be repaired without *too* much trouble I think. That
upgrade step is the last one
to upgrade to 1.22 completely. So, options are:
1. Hand-edit the agent's config file so it thinks it's finished upgrading.
2. Fix Mongo so the upgrade step thinks it has nothing to do.
3. Wait for a fix to Juju. I'm not sure how long that'll take, as we're
all about to travel. I've just filed:
https://bugs.launchpad.net/juju-core/+bug/1441478
#1 will work, but will mean that you'll have no availability-zone
information in your instances.
I'm not sure if that'd cause any immediate problems (Eric?), but it will
mean that charms won't
be able to take advantage of that information.
#2 would be preferable; this would involve opening the Juju state database
with the mongo
shell, and updating all documents in the "instancedata" collection so that
they have "availzone"
fields.
Cheers,
Andrew
