How to Install Linux Kernel 4.13 in Ubuntu 16.04 & Higher

Last updated: September 4, 2017

After 7 release candidates, Linux Kernel 4.13 was finally released yesterday afternoon. Linus Torvalds announced that:

So last week was actually somewhat eventful, but not enough to push me to delay 4.13.

Most of the changes since rc7 are actually networking fixes, the bulk of them to various drivers. With apologies to the authors of said patches, they don’t look all that interesting (which is definitely exactly what you want just before a release). Details in the appended shortlog.

Note that the shortlog below is obviously only since rc7 – the _full_ 4.13 log is much too big to post and nobody sane would read it. So if you’re interested in all the rest of it, get the git tree and limit the logs to the files you are interested in if you crave details.

…

New Features in Kernel 4.13:

  • Initial Intel Cannonlake and Coffeelake support
  • Nouveau has HDMI 3D / stereoscopic support.
  • Radeon/AMDGPU DRM updates
  • New HID, audio hardware support
  • New input drivers support.
  • And lots of more other changes and improvements.

How to Install Kernel 4.13 in Ubuntu / Linux Mint:

The mainline kernel PPA has made the new kernel binaries for Ubuntu, available for download at the link below:

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-4.13.0-xxxxxx_all.deb
  2. linux-headers-4.13.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-image-4.13.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

To get the Kernel 4.13 from the command console, run the commands below one by one:

For 64-bit OS:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300_4.13.0-041300.201709031731_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb

sudo dpkg -i *.deb

for 32-bit OS:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300_4.13.0-041300.201709031731_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300-generic_4.13.0-041300.201709031731_i386.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_i386.deb

sudo dpkg -i *.deb

After installed these .debs, restart and enjoy!

Uninstall Linux Kernel 4.13:

Start/restart your machine and select boot with the previous kernel in Grub2 -> Advanced menu. Then use Ubuntu Tweak, or other system tool to remove the Kernel 4.13, or you may see this how to remove old kernels tutorial.
