[Bug 2053060] Re: Please remove duplicated package

[Mirko Ferrati]

** Description changed:

  ROS Upstream developers/maintainers have been already providing debian packages from their PPA since 10+ years ago.
  See for example the installation instructions and some forum pages:
  https://docs.ros.org/en/ros2_documentation/iron/Installation.html
  https://gazebosim.org/api/gazebo/6.1/install.html
  
  Due to this duplication between the official installation instructions
  and the packages in Ubuntu Archive, the community have been reporting
  issues and there have been complaints for years about this. It also
  affected how Canonical-Ubuntu was perceived by users, and we fully
  understand them since a lot of internal knowledge is needed to be able
  to figure out what is happening.
  
  Someone thinks they come from Canonical directly:
  https://discourse.ros.org/t/canonical-built-ros-packages/4316
  
  A collection of questions from ROS users in answers.ros.org (similar to stackoverflow for ROS) related to errors because of these packages:
  https://discourse.ros.org/t/upstream-packages-increasingly-becoming-a-problem/10902
  And I report the list here (see the page above for the links)
  - "Missing packages after installing rosdep based on python3-rosdep2 in Noetic"
  - "Command ‘roswtf’ not found,installation failed."
  - "roscore not working (upstream packages)"
  - "catkin_make , python-catkin-pkg doesn’t work"
  - "Roscore fails after restart"
  - "How to install rosbash in ros-noetic ?"
  - "Installing ROS: apt install cannot find any distributions"
  - "Unable to locate package ros-noetic-desktop-full"
  - "PopOS support"
  
  Users still complaining in the most recent version and again thinking the packages come from Canonical:
  https://discourse.ros.org/t/ros-and-ubuntu-22/33729
  
  We agreed to remove those from Ubuntu and let upstream maintainers manage their PPA so no collisions happen and we reduce the user confusion between Canonical-Ubuntu and OSRF about ROS.
  This is not the only package to be removed, in fact the entire ROS dependency tree accounts for hundreds of packages.
  I managed to find some roots and will open a bug ticket in each of them as soon as we agree on the process for removal in this bug ticket
  
  https://packages.ubuntu.com/source/noble/ros2-rcutils (this one)
  https://packages.ubuntu.com/source/noble/ros-roscpp-core
- https://packages.ubuntu.com/source/noble/ignition-math
+ https://packages.ubuntu.com/source/noble/ignition-math which should be a dependency of the next one 
+ https://packages.ubuntu.com/source/noble/ignition-cmake
  https://packages.ubuntu.com/source/noble/ros-std-msgs
  https://packages.ubuntu.com/source/noble/ros2-ament-package
  
  https://packages.ubuntu.com/source/noble/apriltag (to be verified with upstream if they want to keep duplicates or not)
