I think you're mixing up terms "kernel version" and "ubuntu release version". 22.10, 24.04 etc. are Ubuntu Release Versions.

Your best bet is to upgrade the system semi-manually, the steps are:

0. run your usual system and/or data backup

1. Check your current apt repositories, perhaps make a "quick backup" of them and then disable any obscure/non-ubuntu repos and just generally have e look for any issues there...:

• example of quick apt directory backup

  sudo tar cJf ~/etc_apt.tar.xz /etc/apt
  

• the repos are in these dirs:

  /etc/apt/sources.list

  /etc/apt/sources.list.d/*.list

2. get the system as up-to-date as possible on the current version:

    sudo apt update
    sudo apt upgrade
    sudo apt dist-upgrade
   

3. adjust behaviour of release upgrades - in file /etc/update-manager/release-upgrades - change the Prompt= value to Prompt=never

4. Since 22.10 is no longer supported, you will need to upgrade to 22.04 LTS (Long Term Support) directly. You can do this by running:

    sudo do-release-upgrade -d
   

Proceed with upgrade, then do cleanup and reboot:

    sudo apt autoremove
    sudo apt clean
    sudo reboot

5. Check system after reboot, review the modified system config files, reiterate 1-4 or try to revert the value of Prompt= in the file /etc/update-manager/release-upgrades and run another do-release-upgrade until you get to the desired/newest version of Ubuntu Release.
