It seems like there is a problem with the mirror you are trying to access. You can either add more mirrors to /etc/yum.conf or wait until the mirror is fully functional again.

ok how do i add more mirrors to yum.conf i was afraid to guess and try to do it i will mess up my computer

try another mirror near you.

http://fedora.redhat.com/download/mirrors.html

edit /etc/yum.conf and add the mirror-repo or put it in a separate file named mirrorname.repo for example in /etc/yum.repos.d

example for the newly released fedora-extras:

cat /etc/yum.repos.d/fedora-extras.repo

now it says i dont have permission to write to that folder:confused: :(

Thats because you need to be root to edit system files. Switch to root in a console using the "su" command then edit the file.
