[unknown] ping mirrors.redcorelinux.org/kaosx
That is not an url that ping can use anyway, test with something like ping 1.1.1.1
or at least use ping mirrors.redcorelinux.org
, if that resolves fine, adjust your etc/pacman.d/mirrorlist
to select another mirror if fosshost still does not give the needed core.db. Also make sure to sudo pacman -Syy
to force a sync (and needed when changing mirrors).
pacman -Suu
has absolute nothing to do with this thread, no idea why you need it (and if this is a case of constant switching between the build and stable repos, complete wrong thread to reply to).
