https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f0b60bfa952458286f43a63c07b0eea170b2cc95



sc@ubuntu-16-04-lts:~$ uname -sr
Linux 4.10.0-28-generic
sc@ubuntu-16-04-lts:~$


Update to current Distro 

Ubuntu 16.04.05 LTS (dec 2017) has:

sc@ubuntu-16-04-lts:~$ uname -sr
Linux 4.10.0-28-generic

Another example (Proxmox 5.1)

root@cvm65:~# uname -r
4.13.4-1-pve

Let's update it

root@ubuntu-16-04-lts:~# apt update
root@ubuntu-16-04-lts:~# apt upgrade -y
root@ubuntu-16-04-lts:~# reboot

Result is kernel update, but anyway old enough:

sc@ubuntu-16-04-lts:~$ uname -sr
Linux 4.10.0-40-generic

Update to latest Kernel

Manual update

1) Go here: http://kernel.ubuntu.com/~kernel-ppa/mainline/
2) Download 3 (maybe 4) debs to a folder somewhere:
mkdir kernel
$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-headers-4.14.0-041400_4.14.0-041400.201711122031_all.deb
$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-headers-4.14.0-041400-generic_4.14.0-041400.201711122031_amd64.deb
$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-image-4.14.0-041400-generic_4.14.0-041400.201711122031_amd64.deb
3) cd /path/to/folder/where/you/put/the/debs
dpkg -i *.deb
dpkg -i linux-*.deb
update-grub
reboot now

Script update

curl https://raw.githubusercontent.com/muhasturk/ukupgrade/master/ukupgrade > ukupgrade
chmod +x ./ukupgrade
!! Edit ./ukupgrade, because it contains reboot after update!!./ukupgrade
