Hi William -<div><br></div><div>This error occurs when a user tries to create the beginner_tutorials package in a write protected directory, such as in the example link you provided /opt/ros/cturtle/stacks. There is no package in the repo called beginner_tutorials, a user needs to create the beginner_tutorials package somewhere they have write permissions, say for example a home directory. After the user has created the package, they will need to follow the rest of the tutorial to add the package path to your ROS_PACKAGE_PATH. As suggested in the nabble link you provided. </div>
<div><br></div><div>The tutorials are an editable part of the wiki and everyone from the community is welcome contribute and make changes when needed. BUT it is very important that the changes you make to the wiki are the correct solution to the problem you encounter when using or learning ROS. If you are unsure, send a message to ROS users and the community will help you and/or update the wiki.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I have some friends that are trying out ROS by doing the tutorials and in the very first tutorial there is a permissions problem cause due to beginner_tutorials being shipped as a binary file now.  Because of that it is put in /opt/ros/... and normal users cannot write to those directories, and so when they are instructed to use roscreate-pkg for the first time they get a permission error, see nabble: <a href="http://ros-users.122217.n3.nabble.com/OSError-Errno-13-Permission-denied-td1459557.html#a1459588" target="_blank">http://ros-users.122217.n3.nabble.com/OSError-Errno-13-Permission-denied-td1459557.html#a1459588</a>.  <div>


<br></div><div>So my question, if I am so inclined, is: Are the tutorials open for anyone to edit or should changes to the beginner tutorials go through some other channel like the mailing list?</div><div><br></div><div>

Thanks,</div>
