Alad [1] filed a deletion request for thunderbird-appmenu-bin [2]: The AUR is not here to self-host your own pacman packages. Host an unofficial user repository if you want to do that. https://wiki.archlinux.org/index.php/Unofficial_user_repositories [1] https://aur.archlinux.org/account/Alad/ [2] https://aur.archlinux.org/pkgbase/thunderbird-appmenu-bin/
