How to update Linux Kernel from 4.4 to 4.8 on Ubuntu 16.04.2?

Posted March 12, 2017 16.7k views
UbuntuDigitalOceanDeploymentUbuntu 16.04

So I just created a new Ubuntu 16.04.2 droplet and I figured, hey, lets update to the latest kernel.

So I read online by Googling around that I have to run this:

sudo apt-get install linux-generic-hwe-16.04

Now the problem is that it wants to install some WiFi packages and thermald. I don’t know why.

What is the proper way to update the Linux Kernel from 4.4 to 4.8 on Ubuntu Server 16.04.2?

You should be able to run:

apt-get -y install linux-image-4.8.0-41-generic linux-image-extra-4.8.0-41-generic

That said, it still attempts to install wireless drivers, specifically wireless-regdb, as shown in the 

crda iw libnl-3-200 libnl-genl-3-200 linux-image-4.8.0-41-generic linux-image-extra-4.8.0-41-generic wireless-regdb

This would be because it’s how the package maintainer set it up, would be my guess as it’s generic and meant to apply to most situations/needs.

    Would it affect the VPS? The VPS doesnt have any wlan devices, so Im guessing it wont do anything.

      Correct, it should not be a problem. But it does add a little extra bloat to the installation.

      Just make a snapshot of you droplet through the DigitalOcean control panel before doing this major upgrade.

      If it’s a new droplet, why not install 16.10 instead, since it comes with 4.8.
      Otherwise, you’ll be running a newer kernel, but older services.
