Juju 1.22.6 is currently replacing version 1.20.11 in Ubuntu trusty-updates.

Juju users who prefer to use Ubuntu LTS packages will get the new version soon.

This update keeps Juju current with public clouds like AWS, Azure, HP
Cloud, and Joyent, and private clouds built with MAAS and OpenStack.
Users of 1.20.11 (and 1.18.1) will find this version works with recent
changes to instance types, regions, zone, and networks in the clouds.

Juju 1.22.6 has many new features introduced since the release of
1.20.11. For details, see the "1.21.1" and "1.22.0" sections at:


The Juju client version on your local machines is mostly independent
from the version of Juju used by your deployed environments. You can
continue to manage your older environments using the new client. You
can upgrade the environments to 1.22.x (or the current stable version
of 1.24.3)  when you are ready. You can upgrade a 1.20.x environment
to 1.22.6 like so:

    juju upgrade-juju --version=1.22.6

You do not need to upgrade to intermediate Juju versions.
