On bionic iBFT system, I switched to ifupdown: $ sudo apt install ifupdown ... $ sudo apt install resolvconf ... $ sudo apt remove netplan.io ... $ sudo vi /etc/network/interfaces ... $ cat /etc/network/interfaces
auto lo iface lo inet loopback source /etc/network/interfaces.d/*.cfg $ sudo update-initramfs -u ... $ sudo reboot ...[system reboots]... $ cat /etc/network/interfaces.d/50-cloud-init.cfg # This file is generated from information provided by # the datasource. Changes to it will not persist across an instance. # To disable cloud-init's network configuration capabilities, write a file # /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following: # network: {config: disabled} auto lo iface lo inet loopback # control-manual ens3f0 iface ens3f0 inet dhcp dns-nameservers 169.254.169.254 gateway 10.0.0.1 $ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN # 127.0.0.53 is the systemd-resolved stub resolver. # run "systemd-resolve --status" to see details about the actual nameservers. nameserver 169.254.169.254 nameserver 127.0.0.53 So this bug can be reproduced on bionic (and later) by replacing netplan with ifupdown and resolvconf. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1806777 Title: cloud-init with iscsi ibft keeps interface at 'manual' so the system gets no dns search domain To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1806777/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
