Original GitHub issue: https://github.com/retspen/webvirtcloud/issues/124

I just upgrade from ubuntu 14.04 to 16.04 and WVC stop working. I update all sturtup scripts to systemd.
So...
When I run manualy: /srv/webvirtcloud/venv/bin/gunicorn webvirtcloud.wsgi:application -c /srv/webvirtcloud/gunicorn.conf.py

I get this one:
bash: /srv/webvirtcloud/venv/bin/gunicorn: /srv/webvirtcloud/venv/bin/python: bad interpreter: Too many levels of symbolic links

python3
https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-16.04-Python-3-Hopes

I have not tried to work without python2. Try it completely removed from the system if it is not needed . Make a clean installation of WVC

http://askubuntu.com/questions/761106/how-to-remove-python-2-in-16-04
to completely remove Python2 and everything that depends on it.

sudo apt purge python2.7-minimal

And re-install dependency and WVC-core

sudo apt-get -y install --reinstall git python-virtualenv python-dev libxml2-dev libvirt-dev zlib1g-dev nginx supervisor libsasl2-modules

clear virtualenv

rm -rf /srv/webvirtcloud/venv

install

cd /srv/webvirtcloud
virtualenv venv
source venv/bin/activate
pip install -r conf/requirements.txt
python manage.py migrate
sudo chown -R www-data:www-data /srv/webvirtcloud

sudo service nginx restart
sudo service supervisor restart
