Athena OS

Repositories

Athena OS leverages on several repositories for accessing to security tools and learning resources in a comfortable manner.

Athena Arch

These repositories are set in /etc/pacman.conf. Here you can choose to add more repositories or remove the existing ones. Each time you edit this file by adding or removing repositories, run sudo pacman -Syy to synchronize the database.

The structure of the Athena OS repository package source is public and available for any contribution.

The source files of each single package is inside the related packages sub-directory. Each package has PKGBUILD file for defining the .pkg.tar.zst package rules and some packages have build.sh file that is used for automating this process by generating the new .pkg.tar.zst, signing it, moving it and its signature to x86_64 folder and delete all the temporary files. The building process is mainly managed by Hephaestus container.

The declaration of Athena repository is defined inside /etc/pacman.conf as:

[athena]
SigLevel = Optional TrustedOnly
Include = /etc/pacman.d/athena-mirrorlist

In Athena, the repository keys and related files, athena.gpg, athena-trusted, athena-revoked, chaotic.gpg, chaotic-trusted and chaotic-revoked files are stored in /usr/share/pacman/keyrings/ folder. athena.gpg file is the public key needed to be imported in order to access to Athena repository, athena-trusted contains the keys to trust, and athena-revoked contains the list of revoked keys in long format. This operation is managed by the installer that will initialize all the keys stored in /usr/share/pacman/keyrings/ folder.

Installation

If you wish to use Athena repository in a different operating system, you can do this by adding the following to your /etc/pacman.conf:

[athena]
SigLevel = Optional TrustedOnly
Include = /etc/pacman.d/athena-mirrorlist

Get the mirrorlist file by running:

sudo curl https://raw.githubusercontent.com/Athena-OS/athena/main/packages/os-specific/athena-mirrorlist/athena-mirrorlist -o /etc/pacman.d/athena-mirrorlist

On the terminal, execute:

sudo pacman-key --recv-keys A3F78B994C2171D5 --keyserver keys.openpgp.org

Finally, trust the imported key by:

sudo pacman-key --lsign A3F78B994C2171D5

Athena Nix

Athena uses stable version of Nixpks repository and it is managed by Nix Channels. To keep the nix channel of the stable version updated, in order to retrieve always the most updated stable packages, run:

Terminal window
sudo nix-channel --update

Athena Nix repository can be used also by flakes. In this manner an host can retrieve a specific configuration set in Athena Nix remotely with minimum effort. The usage of flakes is specified in the main page of Athena Nix repository. To keep update flakes in order to retrieve always the latest updated packages, run:

Terminal window
sudo nix flake update
