In this tutorial, we will show you how to install MAAS on Ubuntu 20.04 LTS. For those of you who didn’t know, MAAS (Metal as a Service) offers cloud-style provisioning for physical servers. It is open-source and free to use, with commercial support available from Canonical. This tool is very useful for normal enterprises in managing virtualized infrastructure. MAAS is supported on Ubuntu, CentOS, Windows, and RedHat operating systems.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. 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 MAAS on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
- 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.
- SSH access to the server (or just open Terminal if you’re on a desktop).

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 MAAS 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
Step 2. Installing MAAS on Ubuntu 20.04.
By default, MAAS is not available on the Ubuntu base repository. Now run the following command below to install MAAS using Snap Store:
sudo snap install maas
Step 3. Installing PostgreSQL.
By default, PostgreSQL is not available to install directly from the Debian 11 base repository. Now we add the official PostgreSQL repository to your system:
echo "deb [signed-by=/usr/share/keyrings/postgresql-keyring.gpg] http://apt.postgresql.org/pub/repos/apt/ bullseye-pgdg main" | sudo tee /etc/apt/sources.list.d/postgresql.list
Next, import the PostgreSQL signing key:
curl -fsSL https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo gpg --dearmor -o /usr/share/keyrings/postgresql-keyring.gpg
Finally, run the following command below to install PostgreSQL:
sudo apt update sudo apt install postgresql-13
After installing PostgreSQL, start the PostgreSQL service and enable it to start at system reboot:
sudo systemctl start postgresql sudo systemctl enable postgresql sudo systemctl status postgresql
After that, we will create a database for MAAS. Here the database is called
maas_db, user named
maasuser, the password is
sudo -u postgres psql create database maas_db; \q
Next, edit the file
sudo nano /etc/postgresql/10/main/pg_hba.conf
Add the following line:
host maas maaszeljko 0/0 md5
Save and close then, start initializing MAAS:
sudo maas init region+rack --database-uri "postgres://maasuser:idroot123@localhost/maas_db"
Next, create the admin account for the web interface, run:
sudo maas createadmin
Step 4. Accessing MAAS Web Interface.
Once successfully installed, open your web browser and type the URL
https://your-ip-addrees. You should see the MAAS interface screen:
