chenxiaolong [1] filed a deletion request for lightdm-mir-bzr [2]: The mir bzr branch has been merged into the main branch. Since the lightdm-ubuntu package includes mir support, this old package is no longer needed. [1] https://aur.archlinux.org/account/chenxiaolong/ [2] https://aur.archlinux.org/pkgbase/lightdm-mir-bzr/
