you appear to have the ROS 1 package repository configured on your Ubuntu Jammy system.

ROS 1 does not support Ubuntu Jammy, hence there is no "release file" there for apt to download.

You'll have to either:

remove the line which says something like deb http://packages.ros.org/ros/ubuntu jammy main from /etc/apt/sources.list, or
remove the .list file from /etc/apt/sources.list.d (note the .d there) which contains that line

then try again.
