HOWTO : Ubuntu Linux Kernel 4.4.0 (Xenial) on Ubuntu 14.04.4

We can use Linux Kernel 4.4.x on Ubuntu 14.04.4 LTS. Kernel 4.x has a good feature that it can live patching the Kernel without rebooting your box. However, it seems that Ubuntu 14.04.x users need to build the kpatch module themselves. Anyway, it is a good news for all Ubuntu 14.04 LTS users.



Meanwhile, the performance of the box will be improved a lot after the upgrade.



Step 1 :



sudo apt-get update



Step 2 :



sudo apt-get install linux-generic-lts-xenial linux-headers-generic-lts-xenial linux-image-generic-lts-xenial linux-tools-generic-lts-xenial



Step 3 :



sudo apt-get remove linux-image-generic-lts-utopic linux-headers-generic-lts-utopic linux-image-generic-lts-vivid linux-headers-generic-lts-vivid



Step 4 :



sudo apt-get autoremove

sudo apt-get autoclean



Step 5 :



sudo update-grub



Step 6 :



Reboot your box.



REMARK



If you are running Croissants (IPS) on Ubuntu 14.04 LTS, you can upgrade the Kernel to 4.4.0 as well. You just follow the captioned steps.



That's all! See you.
