I've been reading up on Hardware Enablement Stack ever since I got the warning a few days ago.

I was not aware of the HWE support cycle prior to this and I have various virtual machines running either 12.04.02, 12.04.03, or 12.04.04.

I update the machines using sudo apt-get update && sudo apt-get upgrade.

Currently this updates and then after reboot I get the message about the end of support and instructions to update.

After Aug. 7 will my standard update routine automatically update the HWE stack for any machines that are using an EOL HWE stack?
If not, will the same instructions supplied in the message still work to update the HWE stack?

This is the message I keep talking about:

Your current Hardware Enablement Stack (HWE) is going out of support

on 08/07/14.  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:

To upgrade to a supported (or longer supported) configuration:



* Upgrade from Ubuntu 12.04 LTS to Ubuntu 14.04 LTS by running:

sudo do-release-upgrade



OR



* Install a newer HWE version by running:

sudo apt-get install linux-generic-lts-trusty linux-image-generic-lts-trusty



and reboot your system.
