I get the same error every time I follow the steps to install Ros. Even though I tried different codes and gpt's solutions, none of them worked. I even deleted Ubuntu and reinstalled it. I would be happy if you help. ~$ sudo apt update

It seems you are trying to install ros-noetic (ROS 1) to Ubuntu-22 (jammy) Which is not supported. Try installing ros-humble (ROS 2) instead. https://docs.ros.org/en/humble/Installation.html

  • $\begingroup$ have you tried removing ROS 1 related ppa from source list and before installing ROS 2? You can chek using following command ls -l /etc/apt/sources.list.d/ | grep ros-. If you get any output, it means there are still some ros-related ppa present that is not supported in ubuntu-22. You can remove those using the following command sudo rm /etc/apt/sources.list.d/ros-* $\endgroup$
