Hi, I am still doing my first steps with a custom buildfarm. Now I got stuck during the “local” build when runing the script generated by “generate\_devel\_script.py”. The code gets checkout out fine and building and testing distro packages like rviz etc works. However with my own package it thows:

Is the something wrong with my buildfarm configuration or did I make a mistake in my package.xml?  
Or can I somehow refresh the cache

sudo apt-get install ros-kinetic-moveit-ros-planning works fine…

Some hint on possible causes would be helpful even if it is just a guess.
