Ubuntu Server 24.04.1 LTS fresh install errors in apt install and upgrade

[Bo Berglund]

I hoped I would be just breezing through making my new server using a freash
24.04.1 LTS installation ISO followed by the usual list of apt installs, but now
here I am again....

Everything seemed OK until I installed:

sudo apt install mosquitto mosquitto-clients

At the end of that I got to this message:

Could not execute systemctl:  at /usr/bin/deb-systemd-invoke line 148.

And the service check yielded this:

sudo systemctl status mosquitto
× mosquitto.service - Mosquitto MQTT Broker
     Loaded: loaded (/usr/lib/systemd/system/mosquitto.service; enabled; preset:
enabled)
     Active: failed (Result: exit-code) since Wed 2025-01-29 12:38:29 CET; 1min
42s ago

So I apt removed these and then ran another apt update / upgrade (did this
yesterday too).

0 upgraded, 0 newly installed, 0 to remove and 23 not upgraded.

So the syetem is *not* up-to-date (is that what stopped mosquitto from
installing?).
And it cannot be upgraded because it just lists that 23 packages are not
upgraded when I try....

I have enrolled a few years ago into the Pro system, but they limit to 5 devices
and I have no idea if there are any left now. Can I fiond out somehow?
And I assume that whenever I do an install it consumes one count and I have done
several over the years...

Why does mosquitto not install and how can I get all packages up-to-date?
