I'm setting up ubuntu server 20.04 on a new pc and I've got an ethernet cable directly in, but during setup it doesn't show ethernet in the "Network connections" setup section, and instead only shows the option to create a bond.

Another way I resolved this is to simply use 21.10 or above. This came with the needed drivers and worked out of the box!

In case you have problems with the REALTEK 8125 (which I assume from your comments) you can search here for more infos.

You might download it from their site

Select the driver 2.5G Ethernet LINUX driver r8125 for kernel up to 5.6 and download it. It needs to be build with make

Note that this driver only works up to Kernel 5.6 (with 5.4 the mainstream kernel it should be ok).
