MarsSeed [1] filed a deletion request for ros-arch-deps [2]: This metapackage is no longer useful. ROS1 Noetic is EOL. 99% of the Noetic AUR packages are unmaintained since 2020-2023.
Many are no longer even buildable, as they only support the freshly EOL Ubuntu 20.04 LTS and Python 3.9. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/ros-arch-deps/
