ROS Debian package builder action

Convert ROS packages to Debian packages.

Inputs

ROS_DISTRO

Required The ROS distribution codename to compile for.

DEB_DISTRO

Required The Debian/Ubuntu distribution codename to compile for.

DEB_ARCH

The architecture (amd64, arm64, ...) to compile for.

REPOS_FILE

Repos file with list of repositories to package. Defaults to sources.repos.

SBUILD_CONF

Additional sbuild.conf lines. For example EXTRA_REPOSITORIES, or VERBOSE. See man sbuild.conf.

ROSDEP_SOURCE

Additional rosdep sources.

SKIP_ROS_REPOSITORY

Don't add packages.ros.org as an apt repository. This allows to build against snapshots.ros.org, for example.

SKIP_PACKAGES

Whitespace separated list of ROS package names not to be build. Note that you need to list downstream dependencies of skipped packages in addition.

SKIP_CHECKOUT

Do not check out the repository. This allows you to manually construct a repos file or workspace.

GITHUB_TOKEN

Set to ${{ secrets.GITHUB_TOKEN }} to deploy to a $DEB_DISTRO-$ROS_DISTRO-$DEB_ARCH branch in the same repo.

SQUASH_HISTORY

If set to true, all previous commits on the target branch will be discarded. For example, if you are deploying a static site with lots of binary artifacts, this can help prevent the repository from becoming overly bloated

PACKAGES_BRANCH

If set, this branch will be used to push the packages instead of $DEB_DISTRO-$ROS_DISTRO-$DEB_ARCH.

GIT_LFS

If set to true, Git Large File Storage will be used to store the generated binaries.

Example usage

name: builder

on:
  workflow_dispatch:
  push:

jobs:
  build_testing:
    runs-on: ubuntu-24.04
    steps:
      - uses: jspricke/ros-deb-builder-action@main
        with:
          ROS_DISTRO: rolling
          DEB_DISTRO: jammy
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Run manually

You can run this action locally on Ubuntu 22.04 or Debian bookworm and newer system.

Run ./prepare -d <deb_distro> -a <arch> once to set up the system and/or adapt to your needs. It will create a ~/.cache/ccache with sufficient rights for the sbuild process, a ~/.sbuildrc, a ~/.cache/sbuild and optionally a ./src with the checked out repos.

Run ./build -r <ros_distro> -d <deb_distro> -a <arch> in a ROS workspace (or the current directory with ./src) to generate the packages into the apt_repo folder. You can run ./build -c to skip already built packages.

Run ./repository -r <ros_distro> -d <deb_distro> -a <arch> to create an apt repository. You can directly use it on your local machine by adapting the path from the generated README.md.

FAQ

The action fails with:

remote: Permission to <REPO_NAME> denied to github-actions[bot].
fatal: unable to access '<REPO_URL>': The requested URL returned error: 403

Make sure the GITHUB_TOKEN has permission to write to the git repository. In the Github webinterface of the project got to Settings, Actions, General. At the bottom there is "Workflow permissions", make sure "Read and write permissions" is selected.

The apt repository is missing some packages

Github has a hard limit of 100MB per file, so the Action deletes bigger files before pushing. You could omit the GITHUB_TOKEN and add your own deploy method as a final step.

The build needs network access

sbuild denies network access during the build by default as per Debian policy 4.9. To allow network access use in the action:

SBUILD_CONF: "$enable_network = 1;"

How to use a private repo as an apt source

Create a Github personal access token with repo scope and do:

echo -e "machine raw.githubusercontent.com\nlogin <TOKEN>" | sudo tee /etc/apt/auth.conf.d/github.conf
