1. Download and verify the public key

You need curl and gpg for this step. Download the key without root privileges:

curl --fail --show-error --location https://alan-null.github.io/apt/archive-key.asc --output archive-key.asc
gpg --show-keys --with-fingerprint archive-key.asc

Public signing key · Full primary fingerprint: 79D57295F80AC84CF56B72872700A3BD4392E7CC

Compare the full primary fingerprint with an independently trusted copy before proceeding. Downloading the key and reading its fingerprint from this page alone does not establish authenticity.

2. Enable the repository

After verifying the key, run:

sudo install -d -m 0755 /etc/apt/keyrings
sudo install -m 0644 archive-key.asc /etc/apt/keyrings/alan-null-archive.asc
sudo tee /etc/apt/sources.list.d/alan-null.sources >/dev/null <<'EOF'

sudo apt update

The archive provides indexes for amd64 and arm64. Package availability and compatibility depend on the individual application and its supported Debian/Ubuntu versions.

3. Install a package

Replace my-tool with the package name from the application's release documentation:

apt-cache policy my-tool
sudo apt install my-tool

Future versions appear through normal APT updates:

sudo apt update
sudo apt upgrade
