We're currently using Ubuntu 22.04.3 LTS (GNU/Linux 5.4.0-153-generic x86_64) and trying to upgrade the kernel to 5.15 or newer. Still even after searching through several posts, wikis, etc, the kernel will stay on 5.4.0. We're out of ideas and hope that someone can point us to the right direction.

What we tried:

  • sudo apt update && sudo apt full-upgrade && sudo apt clean && sudo apt autoremove based on this post
  • sudo apt-get install linux returned E: Unable to locate package linux
  • sudo apt-get install linux-generic returned linux-generic is already the newest version (5.15.0.89.86)
  • sudo apt-get install linux-image-generic returned linux-image-generic is already the newest version (5.15.0.89.86)
  • Using ubuntu-mainline-kernel.sh based of the answer of this post. After testing we uninstalled the kernel via same script.
  • sudo apt install linux-generic-hwe-22.04 based on this post

Still after reboot uname -r will return 5.4.0-153-generic

From what I read in other posts you probably need these information (let me know if something is missing):

/etc/fstab: static file system information.




Use 'blkid' to print the universally unique identifier for a


device; this may be used with UUID= as a more robust way to name devices


that works even if disks are added and removed. See fstab(5).

  • AMD Ryzen 7 1700 Eight-Core Processor

And still after reboot, uname -r will return 5.4.0-153-generic. Final notes: When installing a new package via apt install there is a message that a new kernel has been found and will be used after reboot. But Kernel stays on 5.4.

  • Did you have a dualboot with another linux by any chance? – nobody Nov 23 '23 at 18:05
  • Please check which Kernels are listed in /boot/grub/grub.cfg? Make sure not to edit the file accidentality, just open for viewing using less or so. – noisefloor Nov 23 '23 at 18:39

    Can you also add the output of cat /etc/*release? The 5.4 Kernel was never in Ubuntu 22.04. It started with 5.15. – Terrance Nov 23 '23 at 18:41
  • @Terrance Added the output to my question. There was previously Ubuntu 20.04 installed, however my colleague said he did a clean Ubuntu 22.04 install. – ts-mothership Nov 24 '23 at 08:21
  • @noisefloor I grepped for 5.4 in grub.cfg, no results. But I found two menu entries for 5.15. – ts-mothership Nov 24 '23 at 08:24
  • @nobody There was previously Ubuntu 20.04 installed, however my colleague said he did a clean Ubuntu 22.04 install. Maybe you're right and there are some leftovers on another partition. Do you know how to check it? – ts-mothership Nov 24 '23 at 08:32
  • @ts-mothership: please open a terminal, run sudo update-grub and add the output to your question. – noisefloor Nov 24 '23 at 08:39
  • @noisefloor is already part of the question. – ts-mothership Nov 24 '23 at 08:41
  • Please open a terminal and type dpkg --list | grep linux-image to show all installed kernel versions – if installed correctly, note that the ones with ii in front are actually installed! The ones with rc are just leftover config files and can be purged. – darth_epoxy Nov 24 '23 at 08:45
  • @darth_epoxy Since those infos are already in the question, I formatted my question more, so the commands are better visible. I hope that helps :) – ts-mothership Nov 24 '23 at 08:47
  • @ts-mothership: ok, thx. Overseen this. Based on the output you should see two options in the GRUB menu when booting, one for 6.2 and one for the 5.15 kernel. In case you do not see the entries at boot, edit the file /etc/default/grub and make sure there is a generous timeout set and the menu is visible so you can manually select an entry as necessary. – noisefloor Nov 24 '23 at 08:56
  • Ok short update: it strongly looks like a partition issue. When changing boot sequence, Ubuntu will load Kernel 6.2. Seems there is another partition on same HDD. – ts-mothership Nov 24 '23 at 09:38
  • sudo parted -l and sudo lsblk -f also cat /etc/fstab please. – nobody Nov 24 '23 at 09:49
  • @nobody added partition information to question – ts-mothership Nov 24 '23 at 10:00
  • I see what goes on; but do not know how to repair it in a save way. The previous ubuntu/focal was in bios mode. The new jammy is in uefi mode in my opinion.. 1 1049kB 2097kB 1049kB bios_grub this is a left over from focal. – nobody Nov 24 '23 at 11:32
  • @nobody thanks, that's probably it. We can boot Ubuntu from another partition, then the 6.2 Kernel is selected. We're currently discussing if we're just reinstall with new partitions. If you want, add your comments as answer, then I'll mark your answer as solution. – ts-mothership Nov 24 '23 at 11:35
  • A new install is not a solution. And maybe another one who has much more experience in uefi stuff than me can help with a solution. as a workaround I would set in uefi the EVO drive as 1. bootdevice. And please decide for one kerneltree. – nobody Nov 24 '23 at 12:01

Since we completely reinstalled the server, no answers are needed anymore.

Most likely Ubuntu 22.04 wasn't correctly installed before, an old linux kernel from another partition was chosen in boot instead of the newer, installed kernel.
