Hi,

I just installed ubuntu 14.04.2 (trusty) on my netbook, and followed the directions here ( http://wiki.ros.org/indigo/Installati... ) to install ROS indigo. Then I installed the TurtleBot packages here ( http://wiki.ros.org/turtlebot/Tutoria... ). I test the setup by running roscore on the master machine (different physical machine, but same setup as described), and then minimal.launch on the netbook. It seems to be working for about 15 seconds, but then it crashes when the rapp manager times out.

Does anybody know what might be going on? At first I thought it was a problem with communication between machines, but they can ping each other fine and all environment variables seem to be set:

asdf@asdf:~$ printenv | grep ROS ROS_ROOT=/opt/ros/indigo/share/ros ROS_PACKAGE_PATH=/opt/ros/indigo/share:/opt/ros/indigo/stacks:/home/asdf/thesis/ROS/helloworld/turtlebot_driver_test/:/home/asdf/thesis/LoadManager/catkin_ws/ ROS_MASTER_URI=http://squirrel:11311 ROS_HOSTNAME=asdf ROSLISP_PACKAGE_DIRECTORIES= ROS_DISTRO=indigo ROS_IP=10.8.190.94 ROS_ETC_DIR=/opt/ros/indigo/etc/ros

Here's the output of minimal.launch:

asdf@asdf:~slaunch turtlebot_bringup minimal.launch ... logging to /home/asdf/.ros/log/dfa94692-c740-11e4-8dbb-001c230e5560/roslaunch-asdf-2863.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
