'linux-generic-hwe-18.04' not found after upgrade to 18.04

  • 772

Since upgrading to 18.04 from 16.04 I have been seeing the following message:

➜  ~ hwe-support-status 

You have packages from the Hardware Enablement Stack (HWE) installed that
are going out of support on 2023-04-30.

To upgrade to a supported (or longer-supported) configuration:

* Upgrade from Ubuntu 16.04 LTS to Ubuntu 18.04 LTS by running:
sudo do-release-upgrade -p

OR

* Switch to the current security-supported stack by running:
sudo apt-get install linux-generic-hwe-18.04

and reboot your system.

Does anyone know why this is happening?

  1. No specific hwe or lts linux-image is yet required for 18.04 (so it doesn't exists). Ensure first that linux-image-generic image is installed:

     apt install linux-image-generic

    Then remove old hwe or lts linux images, in my case I did:

    apt purge linux-image-generic-lts-xenial

    Then the hwe-support-status command returns a clean empty response.

  2. I had an old unsupported Linux kernel installed, discovered using 

    # apt policy linux-generic\*

    Remember to run 

    # apt autoremove
    to remove any unused dependencies which may also be picked up by hwe-support-status.
