This morning I accepted the prompt to update my Lubuntu 20.04.5 LTS machine. Following the update, a number of network services have become inaccessible from remote devices:
- SMB (accessing shares from a Windows 10 machine on the same subnet_
- Home Assistant UI (on port 8123)
- Logitech Media Server (on port 9000). This can be accessed from the Ubuntu host, but no longer from other machines on the same subnet.
Any idea which updates might have scuppered the above services, and what I should do next?
EDIT: So this is what's in /var/log/apt/history.log for the update:

I rolled back and re-ran the update. So far it's only the Samba shares that are not working this time (Home Assistant and LMS are fine, so far...)
???
EDIT2: So after restarting the SMBD service, I can access individual shares by name, but I can no longer browse the shares (i.e. if I omit the share name and simply enter the IP address of the server).
Is there a new SMB setting which I need to enable to allow browsing of shares?
