7 years ago Hi! It seems you are using a quite old version of the DoubleDecker python library, basically from a year ago or so. At that point there was a single repository with C, Python, and Java clients. Since then we have separated the different languages into different repositories, https://github.com/Acreo/DoubleDecker-py for the python version. It seems the root of your issues is the "ImportError: cannot import name 'ensure'" line, it seems the PyNaCl-1.1.0.dev1 version does not have the expected module.
Without having the rest of the code and system here to debug (I guess it's the un-orchestrator from polito?), it's a bit difficult to diagnose. Using the latest version of the python library in a clean ubuntu 14.04 docker, this seemed to work for me:
$ docker run -it --rm ubuntu:14.04
# apt-get update
# apt-get install git-core python3-setuptools build-essential libpython3-dev libffi-dev python3-cffi
# git clone https://github.com/Acreo/DoubleDecker-py.git
# cd DoubleDecker-py/
# python3 setup.py install
# python3
>> from doubledecker import clientSafe
>>
Perhaps this approach works better? Then you also get a fresher version of the client, with bugfixes etc. Cheers, Pontus

I am trying to install Double Decker Python version; client only. I follow the following steps : $ git clone https://github.com/Acreo/DoubleDecker.git $ cd DoubleDecker $ git checkout 93ffede $ cd python $ sudo apt-get install build-essential python3-dev python3-setuptools python3-pip libffi-dev $ git clone https://github.com/pyca/pynacl $ cd pynacl $ sudo python3.4 setup.py install $ sudo apt-get install python3-zmq $ cd .. $ sudo python3.4 setup.py install
After installations when I run the code I got the following error
Traceback (most recent call last): File "/home/developer/ orchestrator/ orchestrator_core/dd_server.py", line 2, in
from .doubledecker.clientSafe import ClientSafe
ImportError: No module named 'orchestrator_core.doubledecker'
During handling of the above exception, another exception occurred:

I also try …. But I got the same error

I install DoubleDecker client in python, 10 days before using Ubuntu 14.4 but I didn't get this error. I am looking forward for your kind response. Thanks!
