MarsSeed [1] filed a deletion request for omniorb416 [2]: This orphan legacy version from 2017 was only used by the several- years broken salome modules from 2016. I've submitted deletion requests for those. AUR has a maintained newer omniorb package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/omniorb416/
