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 and serve Aptly repositories containing two packages that we provide to you in the code editor below. 

> **Note:** We have already installed **aptly** 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.

## Subtask I: Create private key

1. Generate a private GnuPG key.

## Subtask II: Manage the first repository

1. Create an Aptly repository named `first-repo`.

2. Add the package `my-first-package_0.1_amd64.deb` to the `first-repo` repository.

3. Create a snapshot of the `first-repo` repository named `first-repo-v01`, and publish it by specifying `packages1` as an endpoint.

## Subtask III: Manage the second repository

1. Create another Aptly repository named `second-repo`. 

2. First, add the package `my-first-package_0.1_amd64.deb` to the `second-repo` repository.

3. Create a snapshot called `second-repo-v01` of this repository and publish it using `packages2` as an endpoint.

4. Now, add the package `my-second-package_0.1_amd64.deb` to the same repository.

5. Create a snapshot of the repository named `second-repo-v02` and publish it by specifying the same endpoint.

## Subtask IV: Serve the repositories

1. You can serve the repository by starting an HTTP server using the following command. (This is not recommended for production use.) 
  ```s
  aptly serve
  ```

Create Aptly repositories and add multiple Debian packages to them with the same and different endpoints.
