To assign the static IP address, create a connection with name ‘static ip’ and use interface as ‘enp0s3’, run beneath command
$ sudo nmcli con add type ethernet con-name 'static-ip' ifname enp0s3 ipv4.method manual ipv4.addresses 192.168.1.189/24 gw4 192.168.1.1
Add the DNS IP to the ‘static-ip’ connection, run
$ sudo nmcli con mod static-ip ipv4.dns 192.168.1.1
To make the connection active, run following nmcli command
$ sudo nmcli con up id 'static-ip'
Output of above nmcli commands would look like below:
