Juju 2.0 is not quite final, as per the risks and timeline outlined in the FFe for Xenial, bug 1545913. As such, we intend to release SRU post-xenial release. This updates juju to the lastest 2.0 milestone version.

[SRU Information]

I tested the package version 2.0~beta6-0ubuntu1.16.04.1 from xenial-proposed and can verify that bug 1572237 is fixed in that package.

As when testing that bug, I used juju and conjure-up to deploy openstack onto lxd containers. I saw no agent-lost errors.

[Adam Stokes (adam-stokes)]

Also tested on a separate system utilizing conjure-up and juju beta6 and saw no agent lost errors for bug 1572237

This bug was fixed in the package juju-core - 2.0~beta6-0ubuntu1.16.04.1
