Hi to All, Thank for your help in solving my problem. But i still unable to find the .bashrc to change the 2nd invocation. Currently, my computer has only 2 .bashrc extension which is attached to this email but they do not have the suitable invocation. Did i overlook it? With thanks, Zhiping Hi Tan, Also based on your first path, you installed cturtle. However when you setup your environment, you are sourcing /opt/ros/boxturtle/setup.sh, which I expect should be /opt/ros/cturtle.sh. Also, I'll note that you have probably added that to your .bashrc twice now, since it errors twice in a row. You could open your .bashrc file and remove the 2nd invocation and change the first invocation to cturtle. The line with the ">>" in it is appending that line to your .bashrc file.
