[Linux] impossible to pass the requirements.txt step

[Fulbert-Millet]

Hi all,

When I try to install on my linux computer (running Ubuntu), I have an error code that leads nowhere on google :

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-p679lidv/cryptography/

I never ran into that error when I was running Nut 2.7 before. Please help me friends.
