How to Install the Linux 5.0 Update on Ubuntu 18.04 LTS

Canonical just out Ubuntu 18.04.3 LTS, which includes Linux 5.0 kernel. This nucleus, also found in Ubuntu 19.04, includes improved hardware support and performance improvements. But, if you have installed the original Ubuntu 18.04 LTSyou will not be automatically updated.

It's a matter of hardware compatibility (HWE)

Software Updater application on Ubuntu 18.04

Here is how it works. Instead of offering the Ubuntu 18.04 LTS original image for years and requiring everyone to update many software after installing it, Ubuntu regularly releases new Ubuntu 18.04 installation programs. ISO. This includes the latest software updates that would typically be installed after installing Ubuntu 18.04. Several versions of Ubuntu 18.04 have been released: the original versions 18.04, 18.04.1, 18.04.2 and 18.04.3.

The Ubuntu version 18.04.2 included a new Battery "hardware activation" (HWE). The stack consists of a newer Linux kernel, an graphical server, and graphics drivers. These have not been automatically installed on existing systems to ensure they do not break anything. After all, long-term service versions are a matter of stability. Companies do not necessarily want a new big kernel update coming out of nowhere.

If you installed Ubuntu 18.04 with the help of the Ubuntu 18.04.2 installation program, you will automatically get the Ubuntu 18.04.3 update containing the new Linux kernel. If you installed Ubuntu 18.04 with Ubuntu 18.04.1 or Ubuntu 18.04, you will not automatically get the new Linux kernel.

Whatever the case may be, all Ubuntu 18.04 systems receive most of the same updates. Older ones simply do not have the hardware activation stack.

Do not know which version of Ubuntu you have installed? Ubuntu 18.04.2 was released on February 14, 2019. If you installed Ubuntu later, you probably have the new stack and you will get Linux 5.0 through the standard software update tools.

How to get the new hardware activation stack

You can choose to participate in the hardware activation update if you wish. LTS versions are supposed to be solid and do not change much, so Ubuntu will not install it automatically for you. That said, we expect everything to be fine on almost all existing systems.

To install Linux 5.0 with the new X server and new graphics drivers, launch a terminal and run the following command. You can simply copy and paste into the terminal and press Enter:

sudo apt install – recommends-linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

Enter your password when prompted and type "y" to confirm if necessary. Ubuntu will update the latest system with the latest hardware activation stack.

Installing Linux 5.0 on Ubuntu 18.04

You will need to reboot your system to install the new kernel. Then a quick command uname -r or uname -a show the version of Linux that you are using: Linux 5.0.

Thanks to OMG! Ubuntu for highlighting the Ubuntu version 18.04.3 LTS and its Linux 5.0 kernel.
