Failed removing a subordinate unit

1

I’m trying to remove a subordinate unit, but that is not allowed?

juju remove-unit prometheus-node-exporter/0
removing unit prometheus-node-exporter/0 failed: unit "prometheus-node-exporter/0" is a subordinate
2

The subordinates are linked to the principle units. You cannot remove only 1 subordinate unit. To remove the subordinates use juju remove-relation

3

Perhaps the error message could be more helpful?

Something like: "removing unit xxx/0 failed: unit “xx/0” is related, remove the relation to remove it.
