I installed Ubuntu server 17.10 on a freshly formatted disk. During the install I was asked to configure the wired interface. Ok
After that I installed the meta-package ubuntu-desktop and re-booted. No wired interface available in NetworkManager. Wireless is ok.
I had to change "/etc/netplan/01-netcfg.yaml" from:
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
enp3s0:
dhcp4: yes
to:
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
I just had the same problem...

All is well after a reboot.
