Can't update debian version 7.11

[Brian Yates]

I recently put a Debian 7.11 image on my BeagleBone Black RevC. The image file is : bone-debian-7.11-lxde-4gb-armhf-2016-06-15-4gb.img.
When I try to update, the following error messages appear:
devo@beaglebone:~$ sudo apt-get update

sudo dhclient eth0

(aka looks your network eth0 didn't auto-connect)
