The call to restore-backup -m controller quickly fails. The error is like ERROR cmd supercommand.go:448 model local.functional-backup-restore:admin@local:admin not found This was first seen when the admin model was renamed to controller

Marked as duplicate because symptom may be slightly different but the underlying root cause is tied up in the same code and the fix for bug 1576874 will also address this issue.

This is because of the following lines in cmd/juju/backups/restore.go:

        // Reset current model to admin so first bootstrap succeeds.
        err = store.SetCurrentModel(controllerName, environs.AdminUser, "admin")
        if err != nil {
                return nil, errors.Trace(err)
        }
