首先，这是yum源的问题，最好更新用终端更新 yum update

修改为上海交大的源
/etc/yum.repos.d/sjtu.repo
-----------------------------------------
[Fedora-ftp.sjtu.edu.cn]
name=Fedora 12 - i386
baseurl=http://ftp.sjtu.edu.cn/fedora/linux/releases/12/Fedora/i386/os/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora

------------------------------------------------
然后yum update

sjtu.repo这个是更新文件路径称为源

之后应该是可以正常更新滴……
