How can I restart the network on 18.04 with netplan?












0















I'm trying to do some stuff with docker in 18.04 Bionic Beaver (sever version!) which requires disabling the DNS resolver



sudo systemctl disable systemd-resolved.service
sudo systemctl stop systemd-resolved.service


Since all of the usual network tools don't appear to be available, I was pointed in the direction of netplan, specifically cat /etc/netplan/*.yaml which returned



# 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}
network:
ethernets:
enp0s3:
addresses:
dhcp4: true
version: 2


So, being the lemming that I am I created /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg and populated it with network: {config: disabled} I wanted to restart the network, and the suggestion I kept finding was



sudo netplan apply


which returned:




sudo: unable to resolve host generic: Resource temporarily unavailable




where my hostname is generic. I assume this is because I stopped resolution? But I think I'm back to my original problem because I'm following this guide which says you need to add dns=default to NetworkManager.config. I assume I must add something similar for BB, but I wouldn't know where to put it.
