Bug Description

This is happening on deployment with Ceph on Jammy and adding nrpe-external-master relation.
When that relation is added, this code[0] is triggered, but faililng with installing python-dbus package,
as you can see from the following log. I believe it is now python3-dbus from Jammy.

2022-11-29 01:19:01 INFO juju.worker.uniter.operation runhook.go:149 skipped "nrpe-external-master-relation-created" hook (missing)
2022-11-29 01:19:06 INFO unit.ceph-mon/0.juju-log server.go:316 nrpe-external-master:503: Installing ['python-dbus', 'lockfile-progs'] with options: ['--option=Dpkg::Options::=--force-confold']
2022-11-29 01:19:06 WARNING unit.ceph-mon/0.nrpe-external-master-relation-joined logger.go:60 E: Package 'python-dbus' has no installation candidate

Because of the above error, it will skip installing lockfile-progs package. And because of this the following critical alert is triggered from nrpe.

/var/lib/nagios/cat-ceph-status.txt: does not exist.

    Make sure lockfile-progs package is installed

    Also, drop python-dbus for simplicity since "check_upstart_job" in nrpe
    is not enabled any longer. And the python-dbus package is no longer
    available on jammy either.

        [on focal with systemd]
        $ ls -1 /etc/nagios/nrpe.d/
        check_ceph.cfg

I've been told that the quincy.2 branch instead of quincy is the one to be used for charm publishing from now on.
