Hi, Frank, I just tested the preupgrade from f14 and f15 to f16, this also happened. That is because the mirrorlist address is not correct, you can update it as below: baseurl=http://download.fedoraproject.org/pub/fedora/linux/development/16/x86_64/os/ installurl=http://dl.fedoraproject.org/pub/alt/stage/16-Alpha.TC1/Fedora/x86_64/os/ That works fine.
