I installed initially 22.04.1 (in 2022), and did all updates.

But, the kernel is still 5.15.0-94 while 22.04.3 comes with kernel 6.2...

And lsb_release -a says

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.3 LTS
Release:    22.04
Codename:   jammy

This question seem to address a similar issue, but their kernel is 6.2!

Did I miss a step to get the new kernel(s)?

What can I do to keep 22.04 and have the new kernel 6.2 (safely)?

  • Please [edit] with dpkg --get-selections | grep '^linux'. Have you tried switching to linux-image-generic-hwe-22.04? – Daniel T Feb 11 '24 at 15:45
  • @DanielT edited. I didn't install hwe but that could be a good idea. – Déjà vu Feb 11 '24 at 15:49
  • Yeah, sudo apt install linux-generic-hwe-22.04 should work. Then after rebooting and verifying, you can remove linux-generic if you want – Daniel T Feb 11 '24 at 15:51
  • Thanls - I did hwe on another version a few years ago and I rolled back, don't recall why. Is there a risk to go hwe? – Déjà vu Feb 11 '24 at 15:53
  • I've been using 6.5 (and non-LTS) and it has worked fine for me. Remember that it GRUB will let you chose the previous kernel, so you can roll back at any time to reinstall non-HWE if there is a problem – Daniel T Feb 11 '24 at 15:55
  • Thanks, using systemd-boot instead of grub, and it's great ;-) – Déjà vu Feb 11 '24 at 16:06
  • Your install media dictates the default kernel stack; 22.04.3 media exists that will install with the GA kernel stack (ie. 5.15) as well as HWE (6.2 though as 22.04.4 updates are rolling out it will upgrade to 6.5 post-install quickly). Server & Desktop have different defaults; and with flavor ISOs the install will be GA or HWE depending on media (just as with all LTS releases from 12.04 LTS so this isn't new) – guiverc Feb 11 '24 at 21:01

Thanks to comments, the way to get newer kernels on a LTS older version is to install the HWE version.

For 22.04, the command is

apt install linux-generic-hwe-22.04

  • All of the point releases of 22.04 install the hwe packages by default (even the 22.04.1, which until just recently, I thought didn't). – ubfan1 Feb 11 '24 at 16:18
