I have two laptop at home. Each is running kubuntu 20.04. Each has been updated on a regular basis. The laptops are HP's with Intel I5 processors. One has kernal version 5.15.0-41 generic, the other has kernal version 5.4.0-121 generic. Why are the kernal versions different?

The one running 5.15 isn't Kubuntu 20.04. That kernel version runs Kubuntu 22.04.Using Kubuntu Linux since March 23, 2007

No, 20.04 just recently (last week) upgraded to 5.15 from the previous 5.13.Originally posted by Snowhog View Post

It might depend on when the install was done -- if using the original 20.04 iso, 20.04.0 if you will, iirc this still follows the standard of NOT offering kernel HWE upgrades. However, this is not totally clear, as I thought all desktop installs had HWE enabled by default nowadays.Originally posted by monon View Post
Newer iso releases come with the HWE kernel upgrades baked in, with the next 'point' release image 20.04.5 (in August) having 5.15.
One thing to check for is that you don't actually have these new kernel versions, but for some reason grub is still using the 5.4 as the default kernel choice.
Another is to check that you havelinux-generic-hwe-20.04 installed, which is a meta-package that pulls in the newer kernels. Perhaps this is missing for some reason on the 'old' install.Comment
