Bug Description

A k8s unit was in an error state due to a charm bug. The charm was fixed, and 'juju upgrade-charm --force-units directory' run. Juju reported success: "Added charm "cs:~stub/generik8s-10" to the model".

However, "juju resolved directory/0" did not appear to trigger a new upgrade-charm hook. Further 'juju upgrade-charm' commands fail, as Juju claims the latest version is already deployed. And, interestingly, further 'juju resolved' commands fail, with Juju claiming that the unit is not in an error state. However, 'juju status' disagrees, clearly showing the error state.

ubuntu@blimp:~$ juju upgrade-charm --force-units directory

The charm had yet to spin up a pod, as it was still attempting (and failing) to setup relations needed for the pod config.
