Public bug reported: systemd resolvectl supports resolvconf compatibility mode when invoked as resolvconf. Ubuntu 24.04 apparently no more provides the real recolvconf:
bor@bor-Latitude-E5450:~/tmp$ dpkg-query -S /usr/sbin/resolvconf systemd-resolved: /usr/sbin/resolvconf This version requires the real interface and fails with wg-quick hack: bor@bor-Latitude-E5450:~/tmp$ sudo wg-quick up ./wg0.conf [#] ip link add wg0 type wireguard [#] wg setconf wg0 /dev/fd/63 [#] ip -4 address add 192.168.6.160/32 dev wg0 [#] ip link set mtu 1420 up dev wg0 [#] resolvconf -a tun.wg0 -m 0 -x Failed to resolve interface "tun.wg0": No such device [#] ip link delete dev wg0 bor@bor-Latitude-E5450:~/tmp$ So, wg-quick became unusable on Ubuntu. It worked fine in Ubuntu 22.04.
