Packages are fundamental units of software deployment in Debian and related operating systems. Packaging enables users to deploy your packages using the built-in tools of their operating system.

In this course, you’ll learn about the environment that Debian packages live in, including repositories, package management installation tools, source and binary packages, and the “upstream” concept. Then you’ll learn about the structure and metadata of packages and an efficient way to build Debian packages using the fpm tool. You’ll also learn to use the Debian Build System, including the tools used to create package skeletons and multiple packages from a single code base. You’ll finish with an introduction to repository and package management and integrity.

By the end of this course, you’ll have learned about the Debian package ecosystem and several ways to build and package. This will enable you to seamlessly integrate your packages into existing infrastructure and take your deployment skills to the next level.

Building Debian Packages from the Ground Up

# Task

In this exercise, you are required to create an Aptly repository with two packages in it. You are required to publish and serve it using NGINX. You can then install and use the packages from the  repository served by the web server. 

> **Note:** We have already installed `aptly` and created these two packages for you in the code editor below. We have given you root access in the code editor so you don’t have to type `sudo` before each command.

In order to complete the task, you need to perform the following steps:

1. Generate a private GnuPG key.

2. Create an Aptly repository, and
add the packages `hello-debian_0.1_amd64.deb` and `hello-debian-data_0.1_all.deb` to it.

3. Create a snapshot of the repository  and publish it.

4. Serve your repository with NGINX using the following command (we have already configured the NGINX server for you in the code editor below):
    ```s
    $ service nginx restart
    ```
5. Fetch the information about the packages from the served repository using the `apt-get update` command.


6. Create a new directory called `test`. 

7. Inside the `test` directory, use `apt-get` to install the  packages `hello-debian-data` and the `hello-debian`. 
   ```s
   $ apt-get install <package-name>
   ```
   If your packages are installed successfully, typing `hello` will display the following message:
   ```s
   "Hurrah! We have served and installed packages successfully".
     ``` 

Serve the Debian packages using NGINX and install those packages from the repository.
