Starting from early morning today I am experiencing CI failures that use ros2-testing complaining about:
E: Failed to fetch http://packages.ros.org/ros2-testing/ubuntu/pool/main/r/ros-foxy-ros-workspace/ros-foxy-ros-workspace_1.0.1-1focal.20210422.234610_amd64.deb 404 Not Found [IP: 64.50.233.100 80]
E: Failed to fetch http://packages.ros.org/ros2-testing/ubuntu/pool/main/r/ros-foxy-ros-environment/ros-foxy-ros-environment_2.5.0-1focal.20210422.235055_amd64.deb 404 Not Found [IP: 64.50.233.100 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
@jspricke pointed me that http://packages.ros.org/ros2-testing/ubuntu/dists/focal/main/binary-amd64/Packages is referencing an incorrect version of these two packages that is missing in the server. For example while the server has ros-foxy-ros-environment_2.5.0-1focal.20210423.001810_arm64.deb the packages references to ros-foxy-ros-workspace_1.0.1-1focal.20210422.234610_amd64.deb which does not exist in the server.
