MarsSeed [1] filed a deletion request for arcanist-stable-git [2]: This is an application package for php7, which no longer exists. Another dependency is also missing. There's another package on AUR, 'arcanist-git', working with repo's current 'php' package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/arcanist-stable-git/
