ros_ign in ROS 2 Rolling has not been released on Ubuntu Jammy

[nuclearsandwich]

The ROS 2 Rolling Ridley distribution recently migrated to Ubuntu 22.04 Jammy using the rosdistro migration tool.

This repository is one which failed to bloom during the migration because the ignition dependencies are not yet available in Ubuntu Jammy. Once the Jammy repositories and the rosdep database are updated it should be possible to release this repository in Rolling again by running bloom normally.

Packages which are not released in Rolling may not be automatically added to future stable ROS 2 distributions.

With Ubuntu Jammy not listed as a supported platform for Gazebo V11, I'm guessing Nav2 will have to migrate it's system simulation tests to Ignition. So having ros_ign installable from Rolling for migrating Nav2's CI would be a nice to have.

These need to be done first:

• Release Ignition Fortress for Jammy into packages.osrfoundation.org: Packaging and CI for Jammy gazebo-tooling/release-tools#566
• Port those packages to packages.ros.org
  • similar to Add Ignition Fortress ros-infrastructure/reprepro-updater#128
  • it should be easier with Add a script for generating import configurations from the live Ignition repositories. ros-infrastructure/reprepro-updater#144)
• Add rosdep keys
  • similar to Ignition Fortress rosdep keys ros/rosdistro#31591

Let us know if you need any help while migrating Nav2 to Ignition, @ruffsl , we're happy to provide guidance.

@chapulina just checking, it seems that the first two steps were done (ros-infrastructure/reprepro-updater#143), right?

Are only the rosdep keys missing?

[chapulina]

ros-infrastructure/reprepro-updater#143 seems to be only partial, it has only ign-cmake and ign-math.

We do have debs for all of Fortress available already, and I believe @j-rivero is planning to kick off the reprepro process in the coming days.

I think ros_ign_gazebo needs std_msgs as its dependency. I was just trying out the rolling branch on Ubuntu 22.04 and got a build failure. Package built properly after adding the dependency

ros_ign_gazebo needs std_msgs as its dependency

• See add std_msgs as dependency #242

It should be out on the next sync:

• ros_ign: 0.244.2-1 in 'rolling/distribution.yaml' [bloom] ros/rosdistro#32889
• ros_ign: 0.244.2-1 in 'humble/distribution.yaml' [bloom] ros/rosdistro#32890
