Charm goes into error state when deployed without --trust

[sed-i]

Bug Description

When the charm is deployed without --trust, it goes into error state.

It would be handy if it would block with a message. Example.

To Reproduce

juju deploy ./oathkeeper_ubuntu-22.04-amd64.charm ok --resource oci-image=$(yq eval '.resources.oci-image.upstream-source' metadata.yaml)

Environment

Model  Controller  Cloud/Region        Version  SLA          Timestamp
auth   k8s2        microk8s/localhost  3.1.6    unsupported  14:17:40-05:00

Charm built from main (6c6151e).

Relevant log output

unit-ok-0: 14:12:53.575 ERROR unit.ok/0.juju-log Uncaught exception while in charm code:
