Google:
  linux show nic

First hit:

What we already know is that the interface much likely is called
"enp2s0", your network settings are probably using another name, maybe
"enp3s0" or even "eth0". However, may recommendation to run

  ls -d /sys/class/net/enp?s0

wasn't good. Please run

  ls /sys/class/net/

The above link shows several commands to get network related hardware
information. Some of those commands might not be installed.

Run

  lspci | egrep -i 'network|ethernet'

FWIW can you boot an Ubuntu (flavour) live DVD or live USB stick to
test, if network does work automatically and to test if you get a GUI
automatically by using a live version.

I can't help you with network settings. Ubuntu much likely does use
network manager or systemd by default, while I'm used to my own scripts
to establish Internet access.
