Cannot setup static IP with Raspberry Pi on Ubuntu 20.04 Desktop
I Ubuntu 20.04 Desktop OS running on Raspberry Pi 4. I have connected a printer to the Pi's ethernet port, and I have troubles in assigning a static IP using netplan. The problem is I cannot find the name of the interface card. Right now I have created a static IP using Network Manager and with the below command I can see that it is on eth0 with IP 192.168.123.101. The problem is I can't find the interface card name.

network: version: 2 renderer: NetworkManager As suggesteed by Simon Banks, I changed my file as below. However, I need to add a wifi connection.

Hereafter I did sudo netplan --debug apply and got this output

I use netplan on my raspberry pi's via ubuntu and RPI OS.. Here is a direct cut and paste from my home servers netplan for its static configuration.. So just change the IP/Subnets to match your loca. Netplan does moan about not being able to match the drivers but it does seem to work so don't worry about them.
In order for this to work and not conflict with the broadband routers DHCP assignmentsI've configured it to not use the range 192.168.0.32-192.168.0.253 for DHCP.
