To install PostgreSQL on Ubuntu, follow these steps:

1. Update the package manager index: sudo apt update
2. Install the PostgreSQL package and any required dependencies: sudo apt install postgresql
3. Once the installation is complete, you can create a new PostgreSQL database cluster. To do this, run the following command: sudo pg_createcluster 11 main --start
4. This will create a new PostgreSQL cluster with version 11, using the main configuration. The --start option will start the cluster after it is created.
5. After the cluster is created, you can connect to the PostgreSQL server as the default postgres user: sudo -u postgres psql
6. From here, you can create new databases and users, and perform other tasks.

Note: The version number (e.g., 11 in the example above) and the configuration name (e.g., main) can be customized as needed.
