LTS Enablement Stacks

The Ubuntu LTS enablement stacks provide newer kernel and X support for existing Ubuntu LTS releases. These enablement stacks can be installed manually but are also available when installing with Ubuntu LTS point release media. These newer enablement stacks are meant for desktop and server and even recommended for cloud or virtual images. However, if one wants to remain on the original GA stacks, the options are:

  • Install from a previous 12.04.0/12.04.1/14.04.0/14.04.1 point release and update. Previous releases are archived at http://old-releases.ubuntu.com/

  • Perform an update or upgrade to an LTS release from a previous release.

  • Perform a network install using the netboot images rather than the new <release>-netboot images.

Ubuntu 16.04 LTS - Xenial Xerus

The 16.04.2 and newer point releases will ship with an updated kernel and X stack by default for the desktop. Server installations will default to the GA kernel and provide the enablement kernel as optional.

Ubuntu 14.04 LTS - Trusty Tahr

The 14.04.2 and newer point releases will ship with an updated kernel and X stack by default. If you have installed with older media you can use the following to install the newer HWE kernel derived from 16.04 (Xenial):

Desktop

 sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial 

Multiarch Desktop

If you run a multiarch desktop (for example, i386 and amd64 on amd64, for gaming or Wine), you may find you need a slightly more involved command, like this:

 sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial libgl1-mesa-glx-lts-xenial libgl1-mesa-glx-lts-xenial:i386 libglapi-mesa-lts-xenial:i386 

Server

Install the HWE kernel derived from 16.04 (xenial):

 sudo apt-get install --install-recommends linux-generic-lts-xenial 

Ubuntu 12.04 LTS - Precise Pangolin

The 12.04.2 and newer point releases will ship with an updated kernel and X stack by default. The current and supported hardware enablement stack is comprised of the newer kernel and X stacks from 14.04 (Trusty).

Anyone wishing to opt into the hardware enablement stack for Precise may do so running the following commands:

Desktop

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

Server

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

Check your support status

If you want a tool to determine if your install is still supported please use hwe-supoprt-status as documented on https://wiki.ubuntu.com/1204_HWE_EOL

 hwe-support-status --verbose 

Below contains additional specifics regarding the exact policies and procedures regarding the support, maintenance, and upgrade paths for these hardware enablement stacks.
