Hi, Tried re-installing ROS and it fails: rosinstall /usr/local/electric "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=electric&variant=desktop-full&overlay=no" … A /usr/local/electric/image_common/image_transport/Makefile U /usr/local/electric/image_common Checked out revision 38261. Installing http://svn.pointclouds.org/ros/tags/perception_pcl-1.0.1 to /usr/local/electric/perception_pcl svn: URL 'http://svn.pointclouds.org/ros/tags/perception_pcl-1.0.1' doesn't exist ERROR: Failed to install tree '/usr/local/electric/perception_pcl' Checkout of http://svn.pointclouds.org/ros/tags/perception_pcl-1.0.1 version into /usr/local/electric/perception_pcl failed. I looked at the svn and I don't see the directory, so someone changed something. there is a tag/electric, so maybe it was changed to that. Kevin
