Comment 6 for bug 1498059

So I've updated packages to 1:0.196.15 from -proposed, but now I have no idea how to make it install Xenial stack over my current Wily stack. It just shows some info and quits:

$ hwe-support-status

Your current Hardware Enablement Stack (HWE) is going out of support
on 2016-08-04. After this date security updates for critical parts (kernel
and graphics stack) of your system will no longer be available.

For more information, please see:
http://wiki.ubuntu.com/1404_HWE_EOL

There is a graphics stack installed on this system. An upgrade to a
supported (or longer supported) configuration will become available
on 2016-07-21 and can be invoked by running 'update-manager' in the
Dash.
