Change DNS Server given during Ubuntu 18.04 installation
Edit your netplan configuration file and remove the old dns server names and add new ones. Edit the file with sudo nano /etc/netplan/01-netcfg.yaml
and yours should be similar to the example below:
network:
version:2
renderer: networkd
ethernets:
enp0s3:
dhcp4: true
nameservers:
search: [mydomain, otherdomain]
addresses: [10.10.10.1, 1.1.1.1]
The line of interest is the one that says addresses
under the settings nameserver
. It might also be written like so:
nameservers:
search:
- mydomain
- otherdomain
addresses:
- "10.10.10.1"
- "1.1.1.1"
Change the address there to the one you desire. Make sure to observe the indentations as ther are. Now after thatv save the file and aplly the changes:
sudo netplan --debug apply
