3 years ago Hi @ranjitkathiriya ! Sorry for the late reply but I was off for a couple of days. Thank you for using robo-gym and for the detailed issue description, it helps a lot!
It looks like something went wrong during the installation of the ROS dependencies, this sometimes happens if some package repositories are temporarily unavailable. Specifically it looks like the ros-noetic-diff-drive-controller package was not installed.
Please verify that by running:
apt list | grep ros-noetic-diff-driveIf my prediction is correct you should get no results from this command.
To solve this you can install the missing package with:
sudo apt-get install ros-noetic-diff-drive-controllerTo be on the safe side (maybe also other packages didn't get installed) I would run again the following lines:
cd $ROBOGYM_WS &&\
sudo apt-get update &&\
rosdep update &&\
rosdep install --from-paths src -i -y --rosdistro $ROS_DISTRO &&\
catkin buildI hope this fixes your issue, please let me know how it goes :)

Hello there,
I am getting an error which is described below. I don't know where I am doing something wrong so I am describing steps that were followed by me.
Steps I followed: Created new ROS workspace and Installed this.
robo-gym Side: Installed and cloned robo-gym to workspace
robo-gym-robot-servers side:
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list' && sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
