Also, if you have destroyed a service, you can't do upgrade-charm, at that
point, you want to make sure your "revision" file in your charm directory
contains a higher number as juju remembers the charms it deploys.  The
"--upgrade" flag on juju deploy can automate that for you, in that case.

See the discussion in this bug, as this behavior surprised me too:
