juju 2.0~beta7-0ubuntu1.16.10.1 (armhf binary) in ubuntu yakkety

 Through the use of charms, juju provides you with shareable, re-usable,
 and repeatable expressions of devops best practices. You can use them
 unmodified, or easily change and connect them to fit your needs. Deploying
 a charm is similar to installing a package on Ubuntu: ask for it and
 it’s there, remove it and it’s completely gone.
 .
 This is a dependency package providing the current version of Juju.
