Odoo 11 is released and this blog is for those who wish to install Odoo 11 in their systems. Since Odoo 11 is supported on python3 and higher versions only, this blog tells you how can one keep Odoo 10 and can run Odoo 11 simultaneously.

1.1 cd /usr/src

1.2 wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz

1.3 sudo tar xzf Python-3.5.2.tgz

1.4 cd Python-3.5.2

1.5 sudo ./configure

1.6 sudo make altinstall

To check if the python is installed correctly in your system, check with the command, python3.5 in terminal.
