You have been subscribed to a public bug: dns-nameservers entry in /etc/network/interfaces is ignored by systemd- resolved-- all of the other settings work, which adds quite a bit of confusion and frustration since Ubuntu recently switched to using netplan.
It would be a **VERY** good idea to add a comment at the top of /etc/network/interfaces that this file is now deprecated, and provide information about the new netplan utility. Something similar was done to /etc/resolv.conf years back. ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- systemd-resolved ignores /etc/network/interfaces on Ubuntu 18.04 https://bugs.launchpad.net/bugs/1823503 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
