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 autoremovebased on this postsudo apt-get install linuxreturnedE: Unable to locate package linuxsudo apt-get install linux-genericreturnedlinux-generic is already the newest version (5.15.0.89.86)sudo apt-get install linux-image-genericreturnedlinux-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-22.04based 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):

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

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.
