Cannot locate the nodes towr_user_interface, rviz_terrain_publisher, goal_pose_publisher and towr_ros_app #43

Hello! When I run the (roslaunch towr_ros towr_ros.launch) command for the first time, only Rviz pops up. xterm doesn't open at all and it seems like ROS cannot locate the nodes (towr_user_interface, rviz_terrain_publisher, goal_pose_publisher and towr_ros_app). It shows the following error messages :
ERROR: cannot launch node of type [towr_ros/towr_user_interface]: can't locate node [towr_user_interface] in package [towr_ros] ERROR: cannot launch node of type [towr_ros/rviz_terrain_publisher]: can't locate node [rviz_terrain_publisher] in package [towr_ros] ERROR: cannot launch node of type [towr_ros/goal_pose_publisher]: can't locate node [goal_pose_publisher] in package [towr_ros] ERROR: cannot launch node of type [towr_ros/towr_ros_app]: can't locate node [towr_ros_app] in package [towr_ros]

I have made all the .cc files executable using the chmod command as well. Any ideas on how I can solve this issue?

You don't have to make any .cc files executable. I suggest you install with sudo apt-get install ros-<ros-distro>-towr_ros then don't forget to source your bashrc in the same terminal and run roslaunch towr_ros towr_ros.launch Best of luck!

Oh I see! I keep getting "E: Unable to locate package ros-kinetic-towr_ros" every time I run "sudo apt-get install ros-kinetic-towr_ros". I am pretty new to ROS, I really appreciate your support.

Oh right, it was a small issue! I ran "sudo apt-get install ros-kinetic-towr-ros" instead of "sudo apt-get install ros-kinetic-towr_ros". Thanks for the help, I'm a big fan of your work!
