acxz [1] filed a orphan request for ros-melodic-rospack [2]: I have tried contacting the maintainer to try to fix the package but it seems to be a difficult job. I believe it might be wise to add a co-maintainer or even change maintainers for this package due to the difficulty of fixing this package.
