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.

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-genericThen remove old hwe or lts linux images, in my case I did:
apt purge linux-image-generic-lts-xenialThen the hwe-support-status command returns a clean empty response.
I had an old unsupported Linux kernel installed, discovered using
# apt policy linux-generic\*
Remember to run
# apt autoremoveto remove any unused dependencies which may also be picked up by hwe-support-status.
