E: Unable to locate package ros-indigo-ros-tutorials

I just installed ros indigo on my raspberry pi following this tutorial: http://wiki.ros.org/ROSberryPi/Installing%20ROS%20Indigo%20on%20Raspberry%20Pi

Now I am trying to go over some beginner level tutorials following this link: http://wiki.ros.org/ROS/Tutorials/NavigatingTheFilesystem

I kept getting errors when I was trying to install ros tutorials. E: Unable to locate package ros-indigo-ros-tutorials

Does anyone know what to do?

Thanks!

I guess you are not using Ubuntu on your raspberry Pi but Raspbian. If it is the case, it might be that they are not available as deb packages. What you should do is cloning them from the Github repository and compiling them in your workspace using Catkin. This tutorial explains how to use a catkin workspace.

Hi, yes I am using Raspbian. I followed your comment and used git clone under the directory ~/ros_catkin_ws/. Then how can I compile those files in my workspace using Catkin? Should I build a package using catkin_make according to the link you attached?

Sorry if these questions are too stupid...

yes go to the root of your workspace (here cd ~/ros_catkin_ws ) and run catkin_make

Hi, I ran catkin_make in my workspace successfully without errors. But after all, as I run sudo apt-get install ros-indigo-ros-tutorialsI get the same error message. There is a ros_tutorials folder in my workspace, and also a ros_tutorial package within the folder. Did I do something else wrong?

I think you have a understanding problem with how in general software is installed in Linux. Once you compile a program from source (here with catkin_make) there is no need to install it using apt-get. Just make sure that your workspace is listed in the ROS path, this can be done

by running source your_workspace/devel/setup.bash
