MarsSeed [1] filed a deletion request for ros-melodic-libmavconn [2]: Dead, EOL package from 2021. Tries to execute a script (fix-python-scripts.sh) from ros-build- tools, which the latter no longer carries. Also its legacy dependency boost1.69 is not compatible with Python 3.11+ and python-numpy 2.0+.
