[John George]

This is a tracking bug for issues in python-libjuju reported in github and blocking juju_2.8-rc1 release testing.

Solutions QA started seeing this with juju_2.8-rc1.
fce fails while executing the Kubernetes validation suite with the following.

Note that @hpidcock merged some code that should address this: https://github.com/juju/python-libjuju/pull/416

Targetted to milestone rc2, as this is being fixed in basically the same time frame, and I'd like to track the issue along w/ all the other rc2 work.

Work to look at more issues, and gate on failures, going on here: https://github.com/juju/python-libjuju/pull/415

[Pen Gale (pengale)]

PR #415 merged. There are still some failing integration tests, which need to be fixed, and possibly some needed updates to mocks in the unit tests.

Having the PR merged will make it easier rather than harder to find and fix these things, however!

[Pen Gale (pengale)]

I think that this one is close. We still have at least one failing integration test, as documented here: https://github.com/juju/python-libjuju/issues/420
