Upgrade from Jammy to Noble breaks iptables-persistent and netfilter-persistent firewall configuration if ufw is also installed pre-upgrade.

from /var/log/dist-upgrade/apt.log:

Description: program for managing a Netfilter firewall
 The Uncomplicated FireWall is a front-end for iptables, to make managing a
 Netfilter firewall easier. It provides a command line interface with syntax
 similar to OpenBSD's Packet Filter. It is particularly well-suited as a
 host-based firewall.

Post do-release-upgrade, iptables-persistent and netfilter-persistent are removed, which breaks any machines that relied on their configuration.
