I'm running 14.04 and installed the 4.02 kernel several months ago because it supported my hardware better (ThinkPad T450s) than the 3.13 kernel.

When I run software update, however, it does not update the 4.x kernel at all -- just the 3.13 one.

I also see that 4.0.x is marked EOL at kernel.org and that 4.1.3 is now listed as the current stable kernel.


  • Do I need to install the newest kernel manually as I did with 4.0 in the first place?
  • And what would happen if I just removed 3.13 from my system? Would that cause the Software Updater to look for 4.x updates?


  • How did you install the 4.02 kernel ? Install an newer kernel the same way =) – Panther Jul 28 '15 at 17:25

I assume, you have installed the kernel manually without a PPA or from the Ubuntu repositories. Therefore you will never get an update and also not, if you remove you 3.x kernel.

To install a supported kernel, follow @Pilot6 answer or search a PPA for a kernel with version 4+.

Or install a kernel via deb packes from here, but you have to repeat this procedure for each new kernel version.

Eg (replace the filenames with you preferred kernel version):

  1. Download the packages

    For 64 bit systems

    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/linux-headers-4.0.0-040000_4.0.0-040000.201504121935_all.deb
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/linux-headers-4.0.0-040000-generic_4.0.0-040000.201504121935_amd64.deb
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/linux-image-4.0.0-040000-generic_4.0.0-040000.201504121935_amd64.deb

    For 32 bit systems

    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/linux-headers-4.0.0-040000_4.0.0-040000.201504121935_all.deb
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/linux-headers-4.0.0-040000-generic_4.0.0-040000.201504121935_i386.deb
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/linux-image-4.0.0-040000-generic_4.0.0-040000.201504121935_i386.deb
  2. Install the packages

    sudo dpkg -i linux-headers-4.0.0-*.deb linux-image-4.0.0-*.deb
  3. Update grub

    sudo update-grub
  4. Reboot your system

  • Many thanks for replies -- I'll give this a try. (And yes, it's how I did it before.) – Dan Gillmor Jul 29 '15 at 1:13
  • Installed without difficulty -- looks like I'll continue to do so until the meta its-wily packages are available. – Dan Gillmor Jul 29 '15 at 1:57

Kernels that are not supported by Ubuntu will never be updated.

You can install the latest stable supported Ubuntu kernel 3.19 by running

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

It will get updates.

If you just remove 3.13, you will get no kernel updates at all.
