Public bug reported:
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.
