Catkin seems to be unavailable for Ros2 Foxy
All of the details are right there in the title. I can't seem to get packages without Catkin, ament is included with Foxy but doesn't seem to work with colcon. Another way around this would be how to use packages without Catkin or ament at all.
For note i'm using Ubuntu 20.04 with the latest version of Foxy installed
