Unfortunately there's been a regression of 54 packages in the Trusty armhf builds: http://repositories.ros.org/status_page/ros_indigo_arm.html?q=REGRESSION

I haven't had a chance to dig in and root cause the regression. At first inspection there's not a clear reason. I've triggered a rebuild of missing packages on the farm and hopefully that will fill in the missing packages overnight otherwise it will need some more digging.
