What do rosdep init and rosdep update do?

  • 772

I would like to know if rosdep init and rosdep update that we perform during ROS installation make any changes outside the ROS environment. Does it update or modify the Debian packages or any other non-ROS components?

I am using Ubuntu 16.04 with ARM architecture.

  1. From the rosdep command reference:

    rosdep init
  initialize rosdep sources in /etc/ros/rosdep.  May require sudo.

rosdep update
  update the local rosdep database based on the rosdep sources.

    Since rosdep update is not run with sudo, it cannot affect apt's package management. rosdep init is run with sudo. However, from the description, it doesn't seem like it touches apt either.
