You’ll be using a couple of different databases as you move through the web development track. The default database that Ruby on Rails uses is SQLite.

1. Open the "Ubuntu" application using the "Start" menu
2. Type sudo apt-get install sqlite3 and press <Enter>

If you were able to run those commands without any issues, continue below.

We also frequently see that students want to deploy their apps to the hosting service Heroku. To do this, though, you will need a different relational database management system called PostgreSQL.

1. Type sudo apt-get install wget ca-certificates and press <Enter>
2. Type wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - and press <Enter>
3. Type sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list' and press <Enter>
4. Type sudo apt-get update and press <Enter>
5. Type sudo apt-get install postgresql and press <Enter> (Note: this may take some time)

If you were able to run those commands without any issues, continue to the next lesson, Configuring GitHub and Flatiron Student Portal on WSL2.
