I have a similar or same issue with Ubuntu 14.04.01 on a desktop with a
Ethernet connection only that worked with Ubuntu 8.04 since 2006. Since
updating, no internet.
I decided to upgrade and did a clean install of Ubuntu 14.04.01 trusty
and I NEVER had Internet again on this dektop. I am sure (tested) that
the cable is OK, the hardware is OK, the internet connection is OK
I have tried a lot of things and a long time spent with excellent
support form the comunity in Italy via IRC did not solve the issue.

There was no trace of trying to connect
I have tried manually starting the eth0 with
sudo dhclient eth0
no connection was possible
I had this long list of DHCPDISCOVER on eth0 to 255.255.255.255 port 67
as described above
I did delete the dhclient.leases file as suggested above, doing
rm /var/lib/dhcp/dhclient.*
this did not solve the issue.
Neither I neither geeks on the IRC channel managed to solve this yet.
I am fairly upset as you can imagine.
thanks
