FabioLolix [1] filed a deletion request for libical2 [2]: Old version released on 2015-12 not compatible with newer version as reported by upstream, fails to build, install in the same place as libical so would break any Arch package, not required by other pkgbuilds [1] https://aur.archlinux.org/account/FabioLolix/ [2] https://aur.archlinux.org/pkgbase/libical2/
