I have Ubuntu 20.04 and I've just installed ROS noetic and catkin.
But each time I do catkin build and I have a list of errors and cannot proceed. Can you guys please help me solve this problem.

apt and pip3 versions of catkin_tools are broken for noetic. Workaround is to install like this:
sudo pip3 install git+https://github.com/catkin/catkin_tools.git
