Answer 1

Try this way for installation

To install PostgreSQL, first refresh your server’s local package index:

sudo apt update

Then, install the Postgres package along with a -contrib package that adds some additional utilities and functionality:

sudo apt install postgresql postgresql-contrib

To make sure it's installed enter this command in the terminal psql --version and it will should output something like this

psql (PostgreSQL) 14.1 (Ubuntu 14.1-2.pgdg20.04+1)
