That is actually an error raised by the SDK:
COMMAND_DENIEDwhen you calledarm(). You couldtry... catcharoundarm()and do something when this error is raised.So it seems like it is working: the drone (here Gazebo) is just refusing to arm for some reason (not ready?) :-). What does the
telemetry.pyexample say?
I actually don't know why, but it works fine today :)
@efischer91: Are you sure you installed it with
pip3.6, by the way?
Definitely. Everything's working fine now. Thank you!

/home/eve/.local/lib/python3.5
You are on Ubuntu 16.04, I presume? You will need Python3.6+, and it seems to me that you have Python3.5.

I'm on Ubuntu 16.04 and have both Python 3.5.2 since it's the pre-installed version and 3.6.7

./other/tools/run_protoc.sh is running python3, which in your case defaults to 3.5. Can you try to edit all occurences of python3 and pip3 in proto.sh?
python3 -> python3.6
pip3 -> pip3.6

This helped with running the shell script, thanks! Now, the next problem is that none of the examples seem to work:

Gazebo simulation is running, backend is running as well. Examples unfortunately don't, even though I did install python3-apt.
