Repository Structure

The APT repository is organized as follows:

• Channels (prefixes): stable/, testing/, pr/

  • stable: Production-ready packages
  • testing: Pre-release packages for testing
  • pr: Pull request builds for CI/CD

• Distributions: noble, jammy, focal, bookworm, bullseye, etc.

  • Ubuntu codenames (noble = 24.04, jammy = 22.04, etc.)
  • Debian codenames (bookworm = 12, bullseye = 11, etc.)

• Components (projects): Independent project namespaces

  • Examples: feelpp-project, mmg, parmmg, ktirio-urban-building, organ-on-chip
  • Each component can have multiple packages
  • Components are isolated - updates to one don't affect others

Client Setup

Add the Feel++ APT repository to your system:

# Download and install the GPG key
curl -fsSL https://feelpp.github.io/apt/feelpp.gpg \
  | sudo tee /usr/share/keyrings/feelpp.gpg >/dev/null

# Add the repository (example: stable channel, noble distribution, multiple components)
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/feelpp.gpg] \
https://feelpp.github.io/apt/stable noble mmg parmmg" \
| sudo tee /etc/apt/sources.list.d/feelpp-mmg.list

# Update package lists
sudo apt update

# Install packages
sudo apt install mmg libmmg5 libmmg-dev parmmg libparmmg5 libparmmg-dev

Note: Specify the components you need in the sources.list line. Available components can be found in the Release file.

Publishing Packages

Quick Start

1. Install the publisher tool:

pip install feelpp-aptly-publisher
# or for development:
pip install -e .

2. Build your Debian packages:

# Your package building process, e.g.:
dpkg-buildpackage -us -uc -b

3. Publish to the repository:

feelpp-apt-publish \
  --component my-project \
  --channel stable \
  --distro noble \
  --debs /path/to/directory/with/debs

That's it! Your packages are now available at:

• https://feelpp.github.io/apt/stable/dists/noble/my-project/

Publishing to Different Channels

Stable (production releases):

feelpp-apt-publish --component mmg --channel stable --distro noble --debs ./debs/

Testing (pre-release testing):

feelpp-apt-publish --component mmg --channel testing --distro noble --debs ./debs/

PR (continuous integration):

feelpp-apt-publish --component mmg --channel pr --distro noble --debs ./debs/

Multi-Component Support

The publisher automatically preserves existing components when adding or updating a component. You don't need to do anything special!

Example scenario:

1. Initial state: Repository has component-a and component-b
2. You publish component-c:

   feelpp-apt-publish --component component-c --channel stable --distro noble --debs ./debs/
   

3. Result: Repository now has component-a, component-b, and component-c

Updating an existing component:

# This will update component-a while preserving component-b and component-c
feelpp-apt-publish --component component-a --channel stable --distro noble --debs ./new-debs/

How it works:

• The publisher reads the current Release file to detect existing components
• It creates temporary repositories for existing components from the pool
• It publishes all components together using aptly's multi-component support
• Both Release and InRelease files are updated consistently

Command-Line Options

feelpp-apt-publish --help

Required options:

• --component NAME: Component (project) name (will be normalized: My_Project → my-project)
• --distro NAME: Distribution codename (e.g., noble, jammy, bookworm)

Optional options:

• --channel NAME: Publication channel (default: stable, options: stable, testing, pr)
• --debs PATH: Directory containing .deb files (default: current directory)
• --pages-repo URL: GitHub Pages repository (default: https://github.com/feelpp/apt.git)
• --branch NAME: Git branch name (default: gh-pages)
• --sign: Enable GPG signing (default: disabled)
• --keyid ID: GPG key ID (required if --sign is used)
• --verbose: Enable verbose logging

Examples:

# Minimal example (uses defaults: stable channel, skip signing)
feelpp-apt-publish --component mmg --distro noble --debs ./debs/

# Full example with all options
feelpp-apt-publish \
  --component my-project \
  --distro noble \
  --channel testing \
  --debs /tmp/my-debs \
  --verbose

# With GPG signing
feelpp-apt-publish \
  --component mmg \
  --distro noble \
  --sign \
  --keyid ABCD1234 \
  --debs ./debs/

Installation

From PyPI (when published)

pip install feelpp-aptly-publisher

From Source

git clone https://github.com/feelpp/apt.git
cd apt
pip install -e .

Development Setup

# Install with development dependencies
pip install -e ".[dev]"

# Or using the setup script
./setup-dev.sh

Development

Running Tests

# Run all tests
pytest

# Run only unit tests (fast)
pytest -m "not integration"

# Run integration tests (slower, tests actual publishing)
pytest -m integration

# Run with coverage
pytest --cov=feelpp_aptly_publisher --cov-report=html

Code Quality

# Format code
black src/ tests/

# Lint
flake8 src/ tests/

# Type checking
mypy src/

Testing

The repository includes comprehensive tests:

• Unit tests (tests/test_*.py): Fast tests for individual components

  • CLI argument parsing
  • Component name normalization
  • Publisher initialization

• Integration tests (tests/test_integration.py): Full workflow tests

  • Single component publishing
  • Multi-component publishing (adding components)
  • Updating existing components
  • All three channels (stable, testing, pr)
  • Channel independence
  • Release/InRelease file consistency

Run the test suite:

# All tests
pytest -v

# Only integration tests
pytest -v -m integration

# Only unit tests (fast)
pytest -v -m "not integration"

Troubleshooting

Components Not Listed in InRelease

Problem: After publishing, packages install correctly but InRelease file doesn't list all components.

Solution: This was a bug in earlier versions. Update to feelpp-aptly-publisher >= 1.1.0 which fixes multi-component support.

Existing Components Lost After Publishing

Problem: Publishing a new component removes existing components from the repository.

Solution: Upgrade to version >= 1.1.0. The new version automatically detects and preserves all existing components.

Package Not Found After Publishing

Problem: Published package but apt update doesn't see it.

Checklist:

1. Check that the component is listed in your sources.list
2. Verify the component appears in the Release file:

   curl -s https://feelpp.github.io/apt/stable/dists/noble/Release | grep Components
   

3. Check that packages exist:

   curl -s https://feelpp.github.io/apt/stable/dists/noble/COMPONENT/binary-amd64/Packages
   

4. Wait a few minutes for GitHub Pages to update (caching)
