I’m very new to Ubuntu, Linux, Netplan, and using my terminal at all. I’m running an Ubuntu 24.04 server on a Raspberry Pi 5, which is hooked up to Ethernet via cable.

According to >ip a, The device is connected to Ethernet.
After running >ip a

It’s also connected to WiFi. The server’s Netplan configuration file (/etc/netplan/50-cloud-init.yaml) doesn’t seem to notice that there’s Ethernet, and doesn’t look like any of the pictures of Netplan config files I see online.

Example of what I think my config file SHOULD look like

Note: I don’t really know what’s dangerous info to share, so I just covered anything that looked sketchy in the images.

I’m trying to set up a static IP, but I’m having trouble as the config doesn’t look like any config in any of the tutorials I see, most notably in that it has no reference to Ethernet, so there’s nowhere to define an address. Other than this, the server works fine.

What my config file looks like – missing any references to ethernet!

I’ve tried manually changing the file to look like the ones I see online, just adding an addresses spot in the wifis and wlan0 sections, rebooting the server, unplugging/replugging the Ethernet cable, running a completely new instance of Ubuntu on a different SD card (and all of the above on that new instance).

**My end goal is to establish a static IP for this server. How can I get my Netplan configuration file to look like the ones I see online? **
