I get 3 messages:

E: the repository'http://archive.ubuntu.com/ubuntu kinetic Release' does not have a Release file
updating from such a repository can't be done securely and is therefore disabled by default
W: see apt-secure (8) manpage for repository creation and user configuration details

Do I create the required repository on my computer? If I create the required repository on my computer what are the configuration details?

Check that you are really using Ubuntu 23.04, codenamed "Lunar Lobster". I say this because you mention "Kinetic", but that is the codename of Ubuntu 22.10 from last year.

If you are still using 22.10 you must upgrade to 23.04 first and only then to 23.10.

If you are not running Kinetic, then:

  1. Make a backup copy of /etc/apt/sources.list
  2. In your preferred editor, change all mentions of kinetic to lunar.
  3. Do the same for all files in /etc/apt/sources.list.d/
  4. Reboot, just as a precaution.
  5. Do a normal full update.
  6. Reboot.
  7. Then try the upgrade again.
