I am trying to go over simulation tutorial but I got problems with launching erlecopter_spawn.launch.
I am using Ubuntu 14.04. The error message is the following:
REQUIRED process [mavros-2] has died!
process has died [pid 24665, exit code -11, cmd /home/nare/sim/catkin_ws/devel/lib/mavros/mavros_node __name:=mavros __log:=/home/nare/.ros/log/ed999112-45a1-11e7-bc29-64006a59af17/mavros-2.log].
log file: /home/nare/.ros/log/ed999112-45a1-11e7-bc29-64006a59af17/mavros-2*.log
Could you please give some suggestion on what could be wrong?
