Your current Hardware Enablement Stack (HWE) is no longer supported

since 2014-08-07.  Security updates for critical parts (kernel and graphics stack) of your system are no longer available.

For more information, please see:

http://wiki.ubuntu.com/1204_HWE_EOL

There is a graphics stack installed on this system. An upgrade to a

supported (or longer supported) configuration will become available

on 2014-07-16 and can be invoked by running 'update-manager' in the Dash.
