MarsSeed [1] filed a deletion request for ros-noetic-ros-controllers [2]: Unused. Unmaintained since 2023. Has not received its last upstream update from 2024. But now the ROS1 (Noetic) distribution is EOL, and many of its packages are broken on and not compatible with Arch Linux, only with Python 3.9 and the EOL Ubuntu 20.04 and Qt 5.12.
