I tried installing Odoo from github repo on Ubuntu 14.04 LTS hosted on a VPS. I followed the steps in the the following link

http://opencloud.pro/instalar-openerp-v8-da-fonte-ubuntu/?lang=en

When I log to the OpenERP web page http://<ip>:8069/ , I get redirected to the page http://<ip>/web/database/selector and I get a 502 Bad Gateway error. Checking /var/log/openerp/openerp-server.log I find the following
