ROS Installation Step 5.1 "Permission denied" [closed]
I am trying to install ROS and now I am at step
on ROS Tutorials. When I write $ rospack depends1 beginner_tutorials into the command line that is just like described in the tutorial I can't see the dependencies that are "roscpp rospy std_msgs".Instead of that, I receive an error list consist of permission denied.
Below you can find a few last commands before I encountered the errors below:
Reference: installation guide
cd ~/catkin_ws/src
catkin_create_pkg beginner_tutorials std_msgs rospy roscpp
cd ~/catkin_ws
catkin_make
. ~/catkin_ws/devel/setup.bash
rospack depends1 beginner_tutorials
What is wrong with it? You can find the errors below:

Can you please update your question with a link to the tutorial that you're referring to
In addition to what @jayess asks: please copy-paste the exact error message into your question instead of paraphrasing it. Use the
editbutton/link to update your original question and please use the Preformatted Text button (the one with101010on it).I have updated the question
What owner and permission does the file (or the containing directory) have? What exact commands did you run before having the problem?
I wrote the exact commands in the question :
$ rospack depends1 beginner_tutorials@salim: @Dirk Thomas is asking what commands you ran before you had this problem.
Thanks @Dirk Thomas, I have updated again.
Still the same question: What owner and permission does the file (or the containing directory) have?
Hi Dirk, I will send the owner and permission information but I do not know which directory's parameters should I check? Because I only write
$ rospack depends1 beginner_tutorialswhile the line showssalim@salim-Satellite-A200:~$The path mentioned in the error message:
/home/salim/.ros/.rospack_cache.f19Z8nI have solved the problem! When I was reading the tutorial about system dependencies, I see
rosdep. It says that if the user have been following the tutorial it is likely that this is the first time user has usedrosdep. It says that just run two following commands:rosdep initrosdep update
