I noticed on the build you linked, you are running in docker container rostooling/setup-ros-docker:ubuntu-focal-ros-rolling-ros-base-latest - i assume we'll need to update setup-ros-docker to provide ubuntu-jammy-ros-rolling-ros-base-latest instead, yeah? That seems to me like it should solve the immediate problem you've actually pointed out here?

[wep21]

Ah, yes, you're right. I missed it. We need ubuntu-jammy-ros-rolling-ros-base-latest.

+1 to this issue, but from using rostooling/setup-ros instead of rostooling/setup-ros-docker.

Action logs from two different repos that started failing recently:

Exact error of CMake failing to find ament_cmake:

  CMake Error at CMakeLists.txt:8 (find_package):
    By not providing "Findament_cmake.cmake" in CMAKE_MODULE_PATH this project
    has asked CMake to find a package configuration file provided by
    "ament_cmake", but CMake did not find one.
  
    Could not find a package configuration file provided by "ament_cmake" with
    any of the following names:
  
      ament_cmakeConfig.cmake
      ament_cmake-config.cmake

    Add the installation prefix of "ament_cmake" to CMAKE_PREFIX_PATH or set
    "ament_cmake_DIR" to a directory containing one of the above files.  If
    "ament_cmake" provides a separate development package or SDK, be sure it
    has been installed.

Edit:

Here's the source of the error, where rosdep fails to find the packages:

  ERROR: the following packages/stacks could not have their rosdep keys resolved
  to system dependencies:
  soccer_vision_msgs: No definition of [vision_msgs] for OS version [focal]

Looks like Focal was removed as a valid Ubuntu distro for Rolling: https://github.com/ros/rosdistro/pull/32036/files#diff-a79d50d14101a47dfc4ea7b0dd7b9446f34b544807d8f0c48cc6a8f07fc3b36aR11. So you need to use Jammy (or build from source on Focal), but the binary packages are currently not available on Jammy: http://packages.ros.org/ros2/ubuntu/dists/jammy/main/binary-amd64/Packages. The workaround mentioned in the issue works though.

Got it, I believe these issues should disappear after a while when the transition process is properly complete. Am I right?

The workaround mentioned in the issue works though.

I can confirm that the work around does work.

For detailed reference for others, to implement the work around, add --os=ubuntu:jammy as seen in
ijnek@80974bd

and change your CI to use your commit or branch, ie.

- uses: ros-tooling/action-ros-ci@80974bd48deac3726e28d7b5fc8a1176481479f5

Yep! I think the binary packages will be available soon.

Yep! I think the binary packages will be available soon.

I'm working on it, though we're hitting bumps in the road
