Comment 1 for bug 1989378

I think this is a valid issue. There are some tools to provide help with migration, but especially the documentation around it needs to be improved.

$ apt install netplan.io
$ systemctl unmask systemd-networkd.service
$ systemctl unmask systemd-resolved.service
$ ENABLE_TEST_COMMANDS=1 netplan migrate
$ netplan try
$ reboot
$ apt purge ifupdown resolvconf
$ ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
