Hi,

cloud-init write dns config in /etc/network/interfaces.d/cloudinit.cfg.

this is working for ubuntu, because /etc/resolv.conf is not a real
file,
but a symlink manage by resolvconf package (or systemd-resolvd I'm not
sure).


you can try to install "resolvconf" package on debian, it should works

it's works for me with resolvconf  and config in lo interface.

#apt install resolvconf
(verify that /etc/resolv.conf is now a symlink)

#echo "" > /etc/resolv.conf

reboot

after reboot /etc/resolv.conf values are same than
/etc/nework/interfaces.d/50-cloud-init
