quequotion [1] filed a deletion request for gconf-sharp [2]: This package is not building. I could provide this package from my own gnome-sharp metapackage, from which it builds successfully. See commented lines in the metapackage's PKGBUILD: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=gnome-sharp#n44 [1] https://aur.archlinux.org/account/quequotion/ [2] https://aur.archlinux.org/pkgbase/gconf-sharp/
