MarsSeed [1] filed a deletion request for ros-noetic-teb-local-planner [2]: EOL, unused, broken. (Last ROS release was in 2020.) Dependency AUR/ros-noetic-libg2o has been an abandoned and broken orphan for the past 2 years. ROS1 (Noetic) is no longer compatible with Arch Linux, only with Python 3.9, Qt 5.12 and the freshly EOL Ubuntu 20.04 LTS.
