Produits Entr'ouvert » Authentic 2

Can't install authentic2 on Debian 8.5 (Jessie) for multiple non satisfied dependencies, the issue is related to the version of django wich is says that require 1.8 not 1.7, even so if i install them more and more dependencies shows up, and nothings go fixes the problem.

Process on fresh installation

i followed this installation :
http://authentic2.readthedocs.io/en/stable/installation.html

for dependencies i installed :
apt-get install build-essential libbz2-dev libsqlite3-dev libreadline-dev zlib1g-dev libncurses5-dev libssl-dev libgdbm-dev libtiff5-dev libjpeg-dev libjpeg62-turbo-dev zlib1g-dev libfreetype6-dev python-dev gettext virtualenv

and to fix compile_scss and build_icon issue
apt-get install ruby-full
and then
gem install sass
gem install compass

the file attached is result of (authentic2-ctl syncdb --migrate) command

Thanks,
