esim installation fatal error

[2112jpc]

I am following the wiki instructions at github.com/uzh-rpg/rpg_esim/wiki/Installation. I managed to install ROS without problems (I am using Ubuntu 20.04 and Noetic was recommended by the ROS site) and I installed catkin. However I am getting the below error when I get to the “Clone this repository and run vcstools” step. Any help would be appreciated.
