yum 安裝gromacs - Linux

小弟是很嫩的新手

用yum安裝gromacs灌了好久都灌不好

Loaded plugins: refresh-packagekit
Could not retrieve mirrorlist
http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-9&arch=i386 error was
[Errno 4] IOError: <urlopen error (-3,

removing mirrorlist with no valid mirrors:
//var/cache/yum/fedora/mirrorlist.txt
Error: Cannot retrieve repository metadata (repomd.xml) for repository:
fedora. Please verify its path and try again

以上是安裝時的error

由於小弟剛接觸程式語言不久

所有很多都看不太懂是什麼意思

請高手指教
