VOLTTRON startup failed/timed out

Question

I am attempting to get Volttron configured on a rasp pi B+

This appears to install Ok: ./scripts/rabbit_dependencies.sh raspbian buster python3 bootstrap.py --drivers --force

But trying to start the Volttron service I am having some issues:

(volttron) pi@raspberrypi:~/volttron $ ./start-volttron
Starting VOLTTRON verbosely in the background with VOLTTRON_HOME=/home/pi/.volttron
Waiting for VOLTTRON to startup..
VOLTTRON startup failed/timed out. Please check volttron.log for details

Any tips going through the commands for the bootstrap process greatly appreciated on Just installing all drivers.

Answer 1

I'm not certain that I've seen exactly this, but I think I've seen something similar where there are error about incompatible c libraries. I believe that previously we saw that when someone was trying to run raspbian on an x86 system, and possibly also when trying to resolve erlang and RMQ dependencies on on raspbian 9. Could you clarify a few things:

• Is this a newly flashed raspbian image, or older (that is, could there be older installed package versions running, or is everything new; also has this system ever successfully run any version of volttron?)
• Are you trying to run with RMQ or ZMQ? It appears that you've tried to install dependencies for RMQ, but configured the platform for ZMQ. Either should work, but would like to minimize the number of things we're tweaking.
• Could you post a pip freeze of the venv you're working with so we can see the exact set of package versiosn?

If you're on the volttron community slack, we can try and debug more real-time there (and try to remember to come back and note the answer here once we've found it).
