Comment 3 for bug 1563611

Thanks Andrew. I think we still want to keep this open and try to simplify the output and not ask for confirmation for something we're not going to let the user do.

    juju destroy-controller ctrl
    ERROR cannot destroy controller "local.ctrl"

    The controller has live hosted models. If you want
    to destroy all hosted models in the controller,
    run this command again with the --destroy-all-models
    flag.

    Models found:
