Which deb files(http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7-rc6-yakkety/) are relevant for 64-bit install. The instructions mention not every 64 filename should be installed(https://wiki.ubuntu.com/Kernel/MainlineBuilds).

You want

  • the ones that have generic NOT low latency in the name and
  • the ones that have amd64 NOT arm64 AND
  • the one that ends with 'all'.

That should give you 3 in total:

  • linux-headers-4.7.0-040700rc6-generic_4.7.0-040700rc6.201607040332_amd64.deb
  • linux-headers-4.7.0-040700rc6_4.7.0-040700rc6.201607040332_all.deb
  • linux-image-4.7.0-040700rc6-generic_4.7.0-040700rc6.201607040332_amd64.deb

To uninstall you just have to remove everything relating to that kernel so, assuming you want to remove the kernel linux-image-4.7.0-040700rc6-generic the standard method is:

Boot a different kernel by selecting an older one from GRUB menu: 'Advanced Options for Ubuntu'

Check you booted a different kernel with uname -r - do not delete the running kernel

Find installed packages relating to the kernel using the name string:

dpkg -l | grep 4.7.0-040700rc6

remove all the listed packages with their names (replace with actual names):

sudo apt-get remove name-of-package1 name-of-package2
dpkg --purge name-of-package1 name-of-package2

run sudo update-grub to clean the boot menu


I prefer to use the locate command to remove upstream kernels, because I'm lazy. After booting a different kernel & checking with uname -r do (replace with the name string of the kernel you want to remove):

sudo updatedb
locate -b -e 4.7.0-040700rc6 | xargs -p sudo rm -r
sudo update-grub

You get an error for files that are not directories (because it's trying to remove them recursively), but it still works, and it cleans everything.

Update: The kernel ppa is not maintained anymore. Now the only way is to download and install the image.deb package manually from below url or build kernel for yourself. http://kernel.ubuntu.com/~kernel-ppa/mainline/

You can add kernel-ppa to repo:

sudo apt-add-repository ppa:kernel-ppa/ppa
sudo apt-get update

Then install the linux kernel pacakges you want to.

sudo apt-get install linux-image-xxx
