MarsSeed [1] filed a deletion request for unity-greeter [2]: Unused, broken orphan. Submitted on 2022-11-22 and never updated. Missing several dependencies. But no other package relies on this: safe to delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/unity-greeter/
