Title:
Netplan and Intel e1000 Driver / I219-V Adapter
Status in linux package in Ubuntu:
Incomplete
Status in netplan.io package in Ubuntu:
Triaged
Bug description:
Since the following change earlier in the year, I have been seeing
issues with Intel's I219-V adapter. It's hard to say whether the
problem is specifically Netplan or down to another change with the
e1000 driver a month or so before. The main reason I am posting this
here is because when machines were switched to Network Manager, the
problem seemed to go away. (Replicated this work-around around with
~10 machines).

* SECURITY REGRESSION: failure on systems without dbus
- debian/netplan.io.postinst: Don't call the generator if no networkd
configuration file exists. (LP: #2071333)
I have had quite a few machines on our network loosing networking
after a period of time. The organisation's network is software defined
(Cisco) and uses 802.1x to authenticate machines to various sub-nets.
Machines get an IP address at boot but loose connection after 3-6
hours. The syslog reports a constant stream of the following message.
The Cisco logs seem to report "unable to obtain an IP address from
DHCP". The machines seems to believe it still has the same IP address
but is unable to communicate.

There is a similiar bug reported on the following post although this
e1000e driver seems to have quite phases where it fails for people. It
seemed that it's a long lived NIC installed over many years, there are
quite a few firmware versions to support over it's lifetime.

There was also a e1000e driver update via the Kernel package, this was
around the same time range the Netplan changed.
