When will 4.2.0 kernel be available for 14.04 LTS?

Solution 1:

The approved answer is wrong. The packages are available right now! Just

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

However note that they will not be officially supported until the 14.04.4 point release is out. Until then they are in the "early preview" phase.

Solution 2:

LTS Enablement Stack

Wily kernel+drivers are now available as stable since 2016, Feb, 18.

You should always wait until Canonical provides a stable backport, like this, of the kernel+drivers released in the edge/six-month releases for the LTS versions: the LTS Enablement Stack.

According instructions, install with:

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

PPA

There is a Canonical kernel team PPA to test the kernel, but you should not use it. The PPA description is clear about it:

This ppa is used for building pre-release and test kernels.

It IS NOT RECOMMENDED that you subscribe to this PPA.

I.e., use it at your own risk. I tested in the past, and got several freezes.

Solution 3:

Short answer: it will be available in main repository for trusty within a week or two.

It is already available in ppa. You can install it by:

sudo add-apt-repository ppa:canonical-kernel-team/ppa
sudo apt-get update
sudo apt-get install linux-generic-lts-wily

It will get to main repository when the maintainers decide to upload it there.

Update: The 4.2 kernels are NOW available in main repositories.
