Postinsttall error

,

Hello,
I tried a version installation testing on a debian 8.2 and during the post install process through the web interface, this one blocks it after putting a password and press the “Go” button. I then try to move the terminal but I get this message:

Traceback (most recent call last):

ImportError: cannot import name NonBlockingStreamReader

I was able to complete the installation commenting on the “Import from .stream NonBlockingStreamReader” then uncommenting the end but I had a bug in the administration interface, and there, now I can no longer log in. In the “yunohost-cli.log” file I have:
