Three systems, two show ls /boot config-6.2.0-33-generic config-6.2.0-34-generic, The third shows config-6.2.0-32-generic config-6.2.0-33-generic. uname -sr is still Linux 6.2.0-33-generic.

I have rebooted third computer and run sudo apt update && sudo apt upgrade repeated times, but no new kernel is installed. All computers are running Ubuntu 22.04 at

Linux ace 6.2.0-33-generic #33~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Sep 7   
10:33:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

The latest kernel version 6.2.0-34 is installed on two of the three computers. The repository sources lists are the same.

You need to run full-upgrade on the third computer to upgrade kernel:

sudo apt update && sudo apt full-upgrade

You should probably look into configuring unattended-upgrades to perform kernel updates.

    Unless they've installed the HWE track of kernels, they won't get the updated HWE kernels. Metapackages do weird things when they're not installed :P – Thomas Ward Oct 07 '23 at 18:46
  • I just don't understand how they could have config-6.2.0-33-generic (question says so) without the HWE kernel enabled. But anyhow, it got fixed for the OP. – Artur Meinild Oct 07 '23 at 19:23
  • I can think of several ways, primary way being manual installation of the corresponding linux-image/linux-headers packages WITHOUT the metapackage (because the metapackage just points at the latest corresponding kernel packages), and that's why it doesn't update. Metapackage does updating, individual kernel packages don't. – Thomas Ward Oct 07 '23 at 19:50

Thanks Artur Meinild, unfortunately sudo apt update && sudo apt full-upgrade didn't fix it.

However, I did find this command:

sudo apt install linux-generic-hwe-22.04

That caused the installation of several new linux-headers including Linux 6.2.0-34-generic. So now the system is up to date.
