FabioLolix [1] filed a deletion request for k3d [2]: Last version was released on 2016-09, last upstream commit on 2019-03 and fails to build, abandoned, k3d-git builds for now. IMO this could be updated to build from the latest commit since new releases are unlikely but I don't have time or interested for that [1] https://aur.archlinux.org/account/FabioLolix/ [2] https://aur.archlinux.org/pkgbase/k3d/
