StreakyCobra [1] filed a deletion request for adwaita-dark-gtk2-git [2]: This packages seems not needed any longer as explained in a comment: «FYI GNOME 3.22 includes an official GTK+ 2 dark theme, this one is no longer necessary.» [1] https://aur.archlinux.org/account/StreakyCobra/ [2] https://aur.archlinux.org/pkgbase/adwaita-dark-gtk2-git/
