Bug Description
Impact
------
When upgrading from Xenial (with all updates installed) to Yakkety/Zesty you will boot to a system without networking - sad!
Test Case
---------
1) Boot a xenial desktop system
2) Ensure network-manager version 1.2.6-0ubuntu0.
3) Upgrade to yakkety or zesty
3.5) Enable -proposed and download the new version of n-m "apt-get download network-manager"
4) Reboot
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.
3) Install nplan, configure to set up static network on an ethernet device using nplan.
4) Upgrade to yakkety or zesty
5) Reboot
6) Observe that your system is still being managed by networkd rather than NetworkManager.
Regression Potential
-------
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.
Original Description
-------
nplan was installed during the upgrade process but I had no network connectivity after upgrading. Apparently, no package wanted to manage my ethernet connection.
