Chazza [1] filed a deletion request for gnome-flashback [2]: gnome-flashback has now been moved back into the community repository so it needs to be removed from the AUR: https://www.archlinux.org/packages/community/x86_64/gnome-flashback/ [1] https://aur.archlinux.org/account/Chazza/ [2] https://aur.archlinux.org/pkgbase/gnome-flashback/
