I am trying to install a program with apt install (or apt-get install) but it always fails due to an error with the avahi-daemon.
See below (ignore the program wine is already installed. This happens with any program I try):
bgc@jadzia:~$ sudo apt-get install wine

wine is already the newest version (5.0-3ubuntu1).
The following packages were automatically installed and are no longer required:
glib-networking:i386 gstreamer1.0-plugins-base:i386 gstreamer1.0-plugins-good:i386
...cut out a lot here as i don't think it's relevant...
ocl-icd-libopencl1:i386 remmina-common shim va-driver-all:i386 vdpau-driver-all:i386
Use 'sudo apt autoremove' to remove them.

I've no clue what avahi-daemon is, but googling has indicated I may need to edit the file /etc/avahi/avahi-daemon.conf. It seems to be something network related (I guess that's the DNS in Avahi mDNS/DNS-SD).
In particular, I've seen suggestions to change the domain-name. Such as here and here. That line in my file was commented out. I've tried uncommenting it, changing it to alocal and localhost, but that has had no effect. Below is my .conf file.

I've also tried starting the service manually, which fails
bgc@jadzia:~$ /etc/init.d/dbus start
Starting dbus (via systemctl): dbus.serviceFailed to start dbus.service: Operation refused, unit dbus.service may be requested by dependency only (it is configured to refuse manual start/stop).
See system logs and 'systemctl status dbus.service' for details.
failed!
And tried editing line 21 that appears in the error message: AVAHI_DAEMON_DETECT_LOCAL=0. Tried changing it to =1 and commenting it out. Still fails.
This issue effectively prevents me from updating or installing a lot of new software. I also can't seem to upgrade to Ubuntu 22.04, perhaps this is related?
Any idea what's causing this and how to resolve it?
