Evolution fails to detect network if system is installed from server media

[Tim Frost]

My home machine has 2 disks, which I have set up using RAID and LVM.
 Because the Ubuntu desktop ISO images don't support RAID/LVM, I used
media created from the Ubuntu server 15.10 64-bit ISO to do the
install, then added ubuntu-desktop to the installed system to get the
packages needed to provide my GUI of choice.  

I recently upgraded from 15.10 to 16.04, and now find that my preferred
mail client, evolution, is in off-line mode and won't switch to on-line 
mode when I invoke it from the normal icons.  It only goes on-line if I
start a terminal session and invoke evolution in that session with the
command
	"GIO_USE_NETWORK_MONITOR=base evolution"
	
I note that the name of the network interface on my system is now
"enp0s25", compared to the historical default of "eth0".

Is the issue related to the interface name change - lspci shows
$ sudo lspci | grep -i eth
00:19.0 Ethernet controller: Intel Corporation 82567V-2 Gigabit Network
Connection
which doesn't seem to account for the new name.


Or is it because networkmanager isn't managing the interface, or
something else?  

What can I do that will allow me to use evolution mail/calendar without
needing to start it from the terminal command line?
