Sebastien: I've confirmed it's a hybrid of two problems...
Firstly, netplan. I had to disable the netplan configurations for the Ethernet interface, and put netplan as such in `/etc/netplan/01-netcfg.yaml`: # This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd (I removed the ethernets: section) I then had to fix Network Manager, as per Bug #1658921 and had to revise /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf to the following: [keyfile] unmanaged-devices=*,except:type:wifi,except:type:wwan,except:type:ethernet After this, and restarting Network Manager, I am able to get Network Manager to handle the Ethernet interface. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1726958 Title: Network Manager does not show any available connection devices, if installed from mini ISO and ubuntu-desktop task. Status in network-manager-applet package in Ubuntu: Confirmed Bug description: This seems to be an issue with Network Manager, but I'm not 100% sure. In testing Ubuntu 17.10 in a VM, installed via the mini ISO and then installing the ubuntu-desktop package and all tasks that TaskSel would have executed, the system lists no managed interfaces. The LAN interface, therefore, is not able to have its config altered out-of-the-box with *just* Network Manager. The interface is not listed in /etc/network/interfaces or any such interface configuration file, and though it gets a DHCP address, there is no way to switch it to a static configuration or DHCP with customized DNS servers without adding a definition into /etc/network/interfaces or similar, based on my testing.
