MarsSeed [1] filed a deletion request for ros-noetic-srdfdom [2]: Fails to build. Upstream is not maintained for Noetic since 2023: last Noetic release version is the current v0.6.4, whereas newer v2.x tags exist only for ROS2. [a]
ROS1/Noetic is also not compatible with Arch Linux, only with the EOL Ubuntu 20.04 LTS. [a]: https://github.com/moveit/srdfdom/tags [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/ros-noetic-srdfdom/
