Installing Odoo in Ubuntu is easy when you use the Debian repository. In order to perform these operations, you may have to be the root user. If you have an account that has the permissions to do so, you can temporarily switch to the root user by opening a Terminal window, and entering the following:
sudo -s
For better security and to guarantee you are installing the correct package, Odoo now signs their distributions. The following command adds the correct key to your Ubuntu installation so that it will recognize the Odoo package:
wget -O - https://nightly.odoo.com/odoo.key | apt-key add -
Next, we want to add the distribution to the /etc/apt/sources.list file with the following command:
echo "deb http://nightly.odoo.com/11.0/nightly/deb/ ...
