I have never installed Ubuntu Server, but I find that surprising. By default these days, interfaces will have "predictable" names, which I think is kind of a misnomer, but afaik should show up in the output of things like "ip a" or "ifconfig -a". It might be that your NIC needs firmware to operate, and that's what prevents it showing up. What NIC is it? What does lspci say?
