I just had the same problem...
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).
# Let NetworkManager manage all devices on this system
All is well after a reboot.

No network connectivity (NIC unmanaged) after upgrade
Status in network-manager package in Ubuntu:
Status in network-manager source package in Yakkety:
Status in network-manager source package in Zesty:
When upgrading from Xenial (with all updates installed) to Yakkety/Zesty you
will boot to a system without networking - sad!
1) Boot a xenial desktop system
2) Ensure network-manager version 1.2.6-0ubuntu0.16.04.1 from -updates is
3) Upgrade to yakkety or zesty
3.5) Enable -proposed and download the new version of n-m "apt-get download
5) Observe you have no network
If you install the version of network-manager from yakkety-proposed
and then reboot you should have a network connection.
1) Boot a xenial desktop system.
2) ensure network-manager version 1.2.6-0ubuntu0.16.04.1 from -updates is
3) Install nplan, configure to set up static network on an ethernet device
4) Upgrade to yakkety or zesty
6) Observe that your system is still being managed by networkd rather than
Any failure to manage ethernet or wireless devices after upgrade, or
issues with the use of netplan in conjunction with NetworkManager
should be investigated as potential regressions. For example, if after
upgrading, ethernet devices are no longer managed, or if devices that
should be explicitly ignored by NetworkManager due to existing user
configuration are now managed, these would indicate a possible
regression caused by this update.
nplan was installed during the upgrade process but I had no network
connectivity after upgrading. Apparently, no package wanted to manage
my ethernet connection.
