How can I restart the network on 18.04 with netplan?
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.
