1. Find the Newtwork Interface name

sudo ip a

Capture the network interface name. It is NOT the lo but something like eth0 or ens160.

2. Create or Edit a Netplan configuration file

sudo vi /etc/netplan/01-netcfg.yaml

The contents should be like this:

network:
    version: 2
    renderer: networkd
    ethernets:
        eth0:
            addresses:
                - 192.168.1.70/24
            nameservers:
                addresses: [8.8.8.8, 8.8.4.4]
            routes:
                - to: default
                  via: 192.168.1.1

Notice here the eth0. Replace it with your network interface name. Also, set the static IPv4 address in the addresses section, with the correct submask bits size (/24 in this case). The correct IP to set depends on your network configuration so use one that works for you. Also in the routes section, in via, set the correct IPv4 for your Gateway (Router).

3. Apply the netplan changes

sudo netplan apply
