graysky [1] filed a merge request for virtualbox-ck-modules [2]: Seems as though AUR v3.3 does not recognize this package anymore but does recognize the two split packages it builds, i.e. virtualbox-ck-host-modules and virtualbox-ck-guest-modules. Please merge virtualbox-ck-modules--> virtualbox-ck-host-modules to retain votes/comments. [1] https://aur.archlinux.org/account/graysky/ [2] https://aur.archlinux.org/pkgbase/virtualbox-ck-modules/
