Been following this tutorial trying to install ROS on my UIbuntu 22.04: http://wiki.ros.org/Installation/Ubuntu

Getting this error when doing the 1.3 part of the tutorial:

E: The repository 'http://packages.ros.org/ros/ubuntu jammy Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Why so? Is it hard to write some normal tutorial which result in no errors? (I don't know what version of ros I'm trying to install, because its not written in installation tutorial page, thats why including ros1 and ros2 tags)
