How to Install the Linux 5.0 Update on Ubuntu 18.04 LTS



  Ubuntu 18.04 LTS

Canonical has just released Ubuntu 18.04.3 LTS with Linux kernel 5.0. This kernel, also included in Ubuntu 19.04, includes improved hardware support and performance enhancements. However, if you have the original Ubuntu 1

8.04 LTS installed, it will not be updated automatically.

It's about Hardware Activation (HWE)

How It Works Instead of offering the original Ubuntu 18.04 LTS image for years and forcing everyone to download a lot of software after update Ubuntu regularly releases new Ubuntu 18.04 installers in ISO form. This includes the latest software updates, which are usually 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.

Ubuntu 18.04.2 included a new hardware enablement (HWE) stack. The stack consists of a newer Linux kernel, an X.org graphics server, and video drivers. These were not automatically installed on existing systems to make sure they did not damage anything. After all, long-term service releases are about stability. Companies do not necessarily want a big new kernel update to come out of nowhere.

If you installed Ubuntu 18.04 with the Ubuntu 18.04.2 installer, you will automatically get the Ubuntu 18.04.3 update with the new Linux kernel. If you have Ubuntu 18.04 with Ubuntu 18.04.1 or the original Ubuntu 18.04 installed, you will not automatically get the new Linux kernel.

In both cases, all Ubuntu 18.04 systems receive the most updates. Older people simply do not have the hardware activation stack.

You are not sure which Ubuntu version you have installed? Ubuntu 18.04.2 was released on February 14, 2019. If you've installed Ubuntu after that, you probably have the new stack and get Linux 5.0 through the standard software update tools.

How to Get the New Hardware Activation Stack

You can enable the hardware activation update if you want. LTS releases should be absolutely stable and not change significantly, so Ubuntu will not automatically install them for you. We assume that this works well on almost all systems.

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

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

Enter your password if You will be prompted to do so and enter "y" to confirm if necessary Ubuntu will be upgraded to the latest system with the latest hardware activation stack.

 Installing Linux 5.0 on Ubuntu 18.04 [19659006] You must reboot your system to install the new kernel, and after doing so, a short command uname -r or uname -a will display the version of Linux, you are running: Linux 5.0.
