MarsSeed [1] filed a deletion request for ros-noetic-common-tutorials [2]: Obsolete, unused developer package from 2021. Fails to build, along with its dependency chain. Only the non-EOL "ros2-*" AUR packages are compatible with Arch Linux. ROS1/Noetic is based on Python 3.9, Qt 5.12, CMake 3 and the EOL Ubuntu 20.04.
