2024-06-24 03:55:23 [ERROR] Command hooks/update-status failed with code 127, output  and error /tmp/juju-exec2307319450/script.sh: line 1: hooks/update-status: No such file or directory

I think the problem is: starting at focal-quincy, ceph-mon is rewrote into operator framework, and update_status is lost.

For example:

→  juju exec --unit ceph-mon-octopus/0 -- ls /var/lib/juju/agents/unit-ceph-mon*/charm/hooks/update-status
/var/lib/juju/agents/unit-ceph-mon-octopus-0/charm/hooks/update-status

→  juju exec --unit ceph-mon-pacific/0 -- ls /var/lib/juju/agents/unit-ceph-mon*/charm/hooks/update-status
/var/lib/juju/agents/unit-ceph-mon-pacific-0/charm/hooks/update-status

 →  juju exec --unit ceph-mon-quincy-focal/0 -- ls /var/lib/juju/agents/unit-ceph-mon*/charm/hooks/update-status
ls: cannot access '/var/lib/juju/agents/unit-ceph-mon*/charm/hooks/update-status': No such file or directory
