First Backup Your network configuration file that contains your DHCP default.
user@svr: cd /etc/netplan [Enter] user@svr:/etc/netplan$ ls [Enter] 50-cloud-init.yaml user@svr:/etc/netplan$ sudo cp 50-cloud-init.yaml 50-cloud-init.yaml-bak [Enter] user@svr:/etc/netplan$ ls [Enter] 50-cloud-init.yaml 50-cloud-init.yaml-bak
Example Configuration for a Static IP. Use Vim or Nano to edit 50-cloud-init.yaml
sudo vim 50-cloud-init.yaml
Edit the file according to the following example, but substituting your network name, Lan IP addresses, Routes (to your router's gateway), and your Nameservers rather than Google's.
network:
version: 2
renderer: networkd
ethernets:
eno1:
dhcp4: no
addresses:
- 192.168.1.10/24
routes:
- to: default
via: 192.168.1.1
nameservers:
addresses: [8.8.8.8, 8.8.4.4]
Apply the network changes:
user@svr: /etc/netplan$ sudo netplan apply
Check the status of the network changes:
if config -a
