yum升级时的问题

lgyaalgy

我安装了yum的axe插件，结果在升级时，出现了这样的问题
axel -a http://ftp.yz.yamagata-u.ac.jp/pub/l...2.fc7.i386.rpm -o //var/cache/yum/fedora/packages/libsidplay-1.36.57-12.fc7.i386.rpm

Package fedora has tried 6 mirrors,Skip plugin!
try to run rm cmd:rm -f //var/cache/yum/fedora/packages/libsidplay-1.36.57-12.fc7.i386.rpm //var/cache/yum/fedora/packages/libsidplay-1.36.57-12.fc7.i386.rpm.st
就是找不着文件，打开相应网址一看呢，地址有问题，也就是说，是yum的配置文件有问题（yum-updates.repo），我想如果修改一下，应该就可以用了，不过不知如何修改。哪位高手帮忙说明一下如何修改，或者解释一下，repo文件里的参数是何意思？如下：
[updates]
name=Fedora $releasever - $basearch - Updates
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/updates/$releasever/$basearch/
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=updates-released-f$releasever&arch=$basearch
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
着重带$符的谢谢！！！
