ROS Noetic is a ROS1 distro that specifically targets Ubuntu 20.04. If you're set on using 22.04 you need to use ROS2 Humble. Otherwise you'll need to downgrade to 20.04.

adding to the previous answer, consider using docker to avoid downgrading from your current ubuntu distro or using ROS2 if your not familiar with it.
