2018-03-28 09:38:09 -0500	marked best answer	ROS - Turtlebot simulator problem: the turtlebot model does not appear on Gazebo. hi, i'm a beginner with ROS world. I use Ubuntu 16.04 (on virtual machine), Kinetic, gazebo 7. When i execute `roslaunch turtlebot_gazebo turtlebot_world.launch`, Gazebo starts and models of the 3D world appear, but there is no turtlebot model! The terminal give me this error: `IOError: [Errno 13] Permission denied: '/home/user/.ros/rosdep/sources.cache/index' [spawn_turtlebot_model-3] process has died [pid 4179, exit code 1, cmd /opt/ros/kinetic/lib/gazebo_ros/spawn_model -unpause -urdf -param robot_description -model mobile_base __name:=spawn_turtlebot_model __log:=/home/user/.ros/log/62c9e862-31d6-11e8-b9a2-080027f2d824/spawn_turtlebot_model-3.log]. log file: /home/user/.ros/log/62c9e862-31d6-11e8-b9a2-080027f2d824/spawn_turtlebot_model-3*.log` I do not understand anything. How to solve?
