The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Odoo open-source ERP on a Ubuntu 20.04 (Focal Fossa) LTS. You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Odoo on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install git python3-pip build-essential wget python3-dev python3-venv python3-wheel libxslt-dev libzip-dev libldap2-dev libsasl2-dev python3-setuptools node-less

Step 2. Installing PostgreSQL.

Install the PostgreSQL package using the apt command:

sudo apt install postgresql postgresql-client

By default, the PostgreSQL service is started automatically after the installation. You can confirm if it is running with the command:

systemctl status postgresql.service

PostgreSQL access graphical interface, you need to install pgAdmin:

sudo apt install pgadmin3

Next, create a PostgreSQL database user for Odoo:

sudo su postgres
createuser --createdb --username postgres --no-createrole --pwprompt USERNAME

Then, you might need to execute the following command to assign superuser rights to a new user:

postgres@ubuntu$ psql

postgres=# \du;
                                    List of roles
 Role name  |                         Attributes                         | 
------------+------------------------------------------------------------+-----
 twink      | Create DB                                                  | {}
 postgres   | Superuser, Create role, Create DB, Replication, Bypass RLS | {}


postgres=# ALTER USER twink WITH SUPERUSER;
ALTER ROLE
postgres=# \du;
                                    List of roles
 Role name  |                         Attributes                         | 
------------+------------------------------------------------------------+-----
 twink      | Superuser, Create DB                                       | {}
 postgres   | Superuser, Create role, Create DB, Replication, Bypass RLS | {}

postgres=# exit
