Public bug reported:
Was running Ubuntu 22.04 as home gateway/firewall with dnsmasq as
dns/dhcp server. Previous upgrade from Ubuntu 20.04 to 22.04 had worked
without issue.
After the upgrade to 24.04.01, systemd-resovled was automatically
enabled. The result was that after a reboot, dnsmasq failed to start, as
systemd-resolved had already bound to the necessary port. This in turn
meant that my entire home network lost connectivity as it was dependant
on dnsmasq running to provide both correct dns and dhcp functionality.
Ideally, during the upgrade process, a check should be made for if
another dns/dhcp service is already enabled, and if so, not enable
systemd-resolved.
