Code review comment for lp:~axino/charms/trusty/ubuntu-repository-cache/xenial-ready

This branch supports both Xenial and Trusty. It should probably be declared as multiseries in metadata.yaml, and moved to a new series-independent home like https://launchpad.net/ubuntu-repository-cache or https://launchpad.net/ubuntu-repository-cache-charm.

The choice of where it ends up is with the maintainer (Robert Jennings is listed, but maybe this needs to be changed to a team since you are doing this fix), and they will need to publish their charm onto the charm store and request to the ecosystem team that it is promulgated to cs:ubuntu-repository-cache (ingestion has been replaced by maintainers publishing directly).
