You have installed python3-catkin-pkg
from the Ubuntu repositories (https://packages.ubuntu.com/bionic/python3-catkin-pkg) which collides with python3-catkin-pkg-modules
from the ROS repositories. Please see http://wiki.ros.org/UpstreamPackages for a detailed description of the problem.
You need to uninstall the upstream packages in order to use the packages from the ROS repos: for this specific package sudo apt purge python3-catkin-pkg
.
I tried to install ros from this link https://index.ros.org/doc/ros2/Installation/Crystal/Linux-Install-Debians/
