MarsSeed [1] filed a deletion request for caja-gksu [2]: Orphan package from 2019. gksu itself has been deprecated and removed from most distros from 2018 on. And replaced by PolicyKit (admin://) based solutions. Nothing depends on this package. Has 2 votes, and only former owner commented in 2020 that he no longer has any use for this.
