How did I get 4.18 Kernel

Asked by tomdean on 2019-06-12

I have two 18.04 LTS systems, both upgraded from 16.04 LS with do-release-upgrade.

The older upgrade'd system has 4.18.0-21-generic kernel. The most recent(today) has the 4.15.0-51-generic kernel. I believe both should have the 4.15 kernel.

The 4.18 kernel is dated May 15/16.
# ls -l /boot | grep '4\.18'
-rw------- 1 root root 4270411 May 15 07:31 System.map-4.18.0-20-generic
-rw------- 1 root root 4268316 May 16 06:14 System.map-4.18.0-21-generic

-rw------- 1 root root 8552184 May 16 07:52 vmlinuz-4.18.0-21-generic

My written log does not show installing the 4.18 kernel or updating it.

Looking at /var/log/apt, I see

What triggered the installation of the 4.18 kernel?

What is the output of the following commands (on both systems):

uname -a
lsb_release -crid
dpkg -l | grep hwe
dpkg -l | egrep ' linux-[shim]'
ubuntu-support-Status
hwe-support-status

(maybe you have installed the HWE kernel on one of the systems, but not the other)

Manfred Hampl (m-hampl) said : #2

Oops, sorry, wrong autocorrect:
one of the commands should be
ubuntu-support-status

That's it. The 4.18 system is on an Intel brick (NUC 7). The other is
on an ASUS P9X79.

Do you still want to see the outputs?

Thanks.

If you are satisfied with the answer, you can close the question without sending the output.
