moabeat [1] filed an orphan request for icaclient [2]: I have tried to contact the maintainer and sent them an updated PKGBUILD that will fix the current error when installing the package. Unfortunately no reply and no update on the package. Flagged out of date since two weeks. [1] https://aur.archlinux.org/account/moabeat/ [2] https://aur.archlinux.org/pkgbase/icaclient/
