Hi, 
Two things to check:
1. What is the name of your network device?  I had an update change the ethernet device name from eth0 to enp3s1 or some such nonsense that is supposed to give consistent naming even if I add in additional adapters into my laptop.  You can grep through dmesg to find out.  Or you can find the name out when you ip addr .
Thanks for the reply.   Name is enp3s0 and has been that since 16.10.  And that name is picked up by dhcp but I can’t get a static address assigned like I could in 16.10


2. Is network maanger running?
Yes, and I’ve played with starting and stopping it as well as a lot of other tricks.  

You can force network maanger to use the interraces file.  The debian site tells you how. https://wiki.debian.org/NetworkManager

Will take a look at this.
3. Okay, I lied there is a third point.  Have a looked through your syslog to find out what's happening?
Using dmesg I see that enp3s0 is shown as up and down many times during startup...  so maybe it is a timing problem.  Will do some more looking at syslog.  I WAS able to use ifconfig to assign the static address that is in the interfaces file and that works as a temp fix so it indicates everything is working except the use of the interfaces file.  But this problem is a showstopper as far as I am concerned.
Good luck.  Thsee things are frustrating.  I had a similar problem getting network manager to work.  The problem was a certain zero byte file was missing.

Hmmm.  Want to tell what file that was?

I've seen a few people complaining about this, but it seems a rare 
issue. There were some networking changes by the Ubuntu devels, so you 
should perhaps search Launchpad for bug reports and add your details 
there. 
 
Kubuntu doesn't handle networking beyond providing the Plasma widgets 
that display what's going on; that is all done at the systemd and 
networkmanager level, by the core Ubuntu developers.
