I wanted to install Ubuntu 20.04.3 LTS Server but everytime I get to the network connections it shows only wifi even tho I already plugged in an ethernet cable, it also wont show any way to set it to ethernet. I continued without a network connection but then I dont have access to internet even after trying to enable it with /etc/network/interface but ifup isnt pre-installed and when checking eth0 it wont find it.
How do I make it use ethernet?

I managed to solve it like this:
First I checked the network devices
It said that my network device is UNCLAIMED so I searched for a driver for my network chip, found and followed this:

after reboot it finally worked as intended.
