Ubuntu 14.04.2

The second point release of Ubuntu 14.04 Trusty Tahr LTS (Long-Term Support) is out today with security fixes, newer kernel (3.16) and X support.

Ubuntu 14.04.2 LTS includes Linux Kernel 3.16 and an updated version of the Xorg display server from the Utopic 14.10 release. These newer enablement stacks are meant for desktop and server use only, and not recommended for cloud or virtual images.

Linux Kernel 3.16 was released in August 2014. It features 64-bit ARM EFI stub support, new Synaptics input driver, initial GK20A support, and more. See this article for details.


To download the .iso files of Ubuntu 14.04.2 and its flavors, go to:



For Ubuntu 14.04 and/or 14.04.1 users, just install all the system updates via Software Updater or run below commands one by one in a terminal (Ctrl+Alt+T):

sudo apt-get update

sudo apt-get upgrade

For the Kernel 3.16 and updated X stack, you have to install below packages manually by running command:

  1. Tnx for this nice tutorial.
    I can’t suspend my laptop after upgrading to Ubuntu 14.04.2.
    How can I fix it?
    (I have a Lenovo z510)

  2. Hi, could you help me, my pc says I am running 14.04.2 but I have Kernel 3.13. I tried to add the packages using the command above but I keep getting this error:

    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.

    • @REW, open Software & Updates utility from the Dash or App Menu, then navigate to Updates tab. There are 4 check-boxes under “install updates from”, make sure the first two “trusty-security” and “trusty-updates” are enabled.

      To avoid umet dependencies, you may disable all third-party PPA repositories under Other Software tab.

      Finally update system cache before installing new kernel and X stack:

      sudo apt-get update

    Thank you so much Ji m for the huge help. Now I have Ubuntu v14.04.2 LTS and with the new kernel v3.16.0-30 generic.

    It’s so easy to do all the steps.

  4. Be careful before installing it, it breaks the wifi of computers with Qualcomm network. I fixed it by following this answer on askubuntu
