Ubuntu – Hardware Enablement Stack (HWE) out of support

12.04hardware-enablement-stackkernel

From yesterday my update manager gives me this message:

Your current Hardware Enablement Stack (HWE) is going out of support
on 07/08/2014. 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/1204_HWE_EOL

But when I try to upgrade the HWE with the command suggested by hwe-support-status --verbose that is

sudo apt-get install linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty

I get dependency errors:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgl1-mesa-glx-lts-trusty : Depends: libglapi-mesa-lts-trusty (= 10.1.3-0ubuntu0.1~precise1) but it is not going to be installed
 xserver-xorg-lts-trusty : Recommends: xserver-xorg-input-all-lts-trusty but it is not going to be installed
                           Recommends: xserver-xorg-video-all-lts-trusty but it is not going to be installed
                           Recommends: x11-xserver-utils-lts-trusty but it is not going to be installed
                           Conflicts: libglapi-mesa:i386 (>= 0~)
E: Unable to correct problems, you have held broken packages.

How can I solve this?

I'm running Ubuntu 12.04.4 LTS 64 bit with kernel 3.5.0-53-generic.

I had the same problem, this is what worked for me

Command:

For amd64:

sudo apt-get install -V libglapi-mesa-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty xserver-xorg-input-all-lts-trusty xserver-xorg-video-all-lts-trusty libgl1-mesa-dri-lts-trusty x11-xserver-utils-lts-trusty libglapi-mesa-lts-trusty:i386 libgl1-mesa-dri-lts-trusty:i386 libgl1-mesa-glx-lts-trusty:i386 libgles2-mesa-lts-trusty libglapi-mesa-lts-trusty mesa-vdpau-drivers-lts-trusty

For i386:

sudo apt-get install -V libglapi-mesa-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty xserver-xorg-input-all-lts-trusty xserver-xorg-video-all-lts-trusty libgl1-mesa-dri-lts-trusty x11-xserver-utils-lts-trusty mesa-vdpau-drivers-lts-trusty libgles2-mesa-lts-trusty libglapi-mesa-lts-trusty

Ubuntu – How does LTS combine with HWE out of support

As far as I can tell you are told to upgrade to 12.04.5.

From the mailing list:

In an effort to support a wider variety of hardware within the 12.04 Ubuntu LTS release, the 12.04.2 and newer point releases in Precise shipped with hardware enablement stacks composed of updated kernels and graphics stacks. The intention has always been for these hardware enablement stacks to only remain supported until the introduction of the kernel and graphics stack derived from 14.04. On August 7, 2014, the 5th and final point release for 12.04 (ie. 12.04.5) will deliver the kernel and graphics stack derived from 14.04. At that time, security updates and bug fixes for older hardware enablement stacks will no longer be provided. All users of older hardware enablement stacks will be encouraged to update to the 12.04.5 hardware enablement stack or fully upgrade to 14.04 proper. For any 12.04 HWE stack users interested in making this migration prior to the August 7, 2014 deadline, we have provided a mechanism to assist with this process. First, please ensure your system is up to date with the latest package updates for Precise. Then, run the command below and follow the instructions which are output:
hwe-support-status --verbose

From the website:

What is HWE?

Hardware Enablement Stacks (HWE) are incorporated into installers for select Ubuntu LTS (Long Term Support) point releases. It is a special Ubuntu feature that provides an LTS release with hardware support introduced in newer Ubuntu releases. For Ubuntu 12.04 the point releases are .2/.3/.4/.5 and the corresponding Ubuntu releases are 12.10/13.04/13.10/14.04.

...

End-of-life (EOL) for 12.04, 12.04.1, and 12.04.5 HWE is April 2017 but for the other HWE stacks it is roughly when 14.04.1 is released: Aug 8, 2014.

How I read this? 12.10, 13.04 and 13.10 are end of life so their HWE are end of life. 12.04 and 12.04.1 use the 12.04 HWE. All other point releases move to the 14.04 HWE.

Seems logical?

Ubuntu – How to opt in to Early Preview of LTS enablement stack

Generally speaking it is done by installing packages like -lts-, e.g. linux-generic-lts-utopic for Ubuntu 14.04.

With kernels it is quite easy. But with graphical stack it is not that straight forwared because of dependencies, especially on 64-bit systems. Commands given in that article are not quite correct in many cases and can remove a lot from you system.

It is reversable. But it is better if you specify which version do you run and which kernel/graphics you want to upgrade. Then it will be possible to give you a more specific guide.

-Updates pocket is a part of Ubuntu repositories. You do not need to do anything to install from there, becuse this part is enabled by default.

For Ubuntu 14.04 kernel from Ubuntu 14.10 is available (3.16). It can be installed by running

sudo apt-get install linux-generic-lts-utopic

Very soon kernel from 15.04 (3.19) will be available. It is in proposed repository, and will get to main sime time next week, I guess. It can be installed by

sudo apt-get install linux-generic-lts-vivid
