Public bug reported: I've just upgraded this machine from Kubuntu 16.04 to Kubuntu 16.10 using the uprading UI. Before the upgrade, I had lo and eth0 in /etc/network/interfaces. After the upgrade, there was only lo, no eth0 anymore, leaving me without a network connection. I had to re-enter eth0 into the file and restart the networking service to get networking functionality again.
