I installed ROS version Lunar on ubuntu 16.04 . I was trying to initializing the catkin work space that this error appeared :

Could neither symlink nor copy file "/opt/ros/lunar/share/catkin/cmake/toplevel.cmake" to "/opt/ros/lunar/catkin_ws/src/CMakeLists.txt":
- [Errno 13] Permission denied
- [Errno 13] Permission denied: '/opt/ros/lunar/catkin_ws/src/CMakeLists.txt'negar

what should I do???

I prefer not to reinstall it and when I use sudo, It's not work

I also create directory in $HOME , but :

negar@negar:/home/ros_working/catkin_ws/src$ catkin_init_workspace Could neither symlink nor copy file "/opt/ros/lunar/share/catkin/cmake/toplevel.cmake" to "/home/ros_working/catkin_ws/src/CMakeLists.txt": - [Errno 13] Permission denied: '/home/ros_working/catkin_ws/src/CMakeLists.txt'

And when I use sudo : sudo: catkin_init_workspace: command not found

not try to make your Catkin workspace in a non-world-writable location. /opt/ros/lunar/catkin_ws is a location only writable by root (or users with similar permissions).

Try to create your workspace in your $HOME directory.

Edit: please add how you created your workspace (ie: the /home/ros_working/catkin_ws directory).

Also include the output of ls -al /home/ros_working/catkin_ws in your update.
