Working on Raspberry Pi2 B Armv7 rev 5 (v7l). Used the link you posted to the install script, didn't work last night around tf2_ros package, removed the 20-default.list file and tried again today and it finished Ok. There were some warnings about liboost conflict, so.1.54.0 with so.1.55.0 but it carried on.
Can't find my Forum password so can't paste from the pi, this is the traceback
rosrun openag_brain main -f default
File "/home/pi/catkin_ws/src/openag_brain/scripts/main", line 10, in module
from openag.couch import Server
ImportError: No module named openag.couch
Update: not sure I mentioned that I have two sd cards set up, the first has the setup for the brain as it has been progressing and was working, at least it was storing the images from my playstation 3 usb cam. Lost track of the brain updates so resorted to installing the docker image on that card which worked apart from storing the usb images, not sure about the sensors as the code for them is what we are trying to develop.
The second card I setup yesterday and reported the above error.
I've returned to the first card and repeated the openag_brain installation(other machines) instructs. ie recreated the catkin_ws , and cloned the repo without, -b ros, as it is reported as not there. everything appears to install, and it reports that all required rosdeps installed successfully.
When I execute rosrun openag_brain main -f default it gives me the same error as above
importError: No module named openag.couch
