[linux]Error: failure: repodata/repomd.xml from fedora: [Errno 256] No more mirrors to try.

在使用fedora17 系统的yum源的时候出现了如下错误：

Error: failure: repodata/repomd.xml from fedora: [Errno 256] No more mirrors to try.

参照网上的做法： （一般yum有变更都需要这两个操作）

yum clean all 

yum clean metadata

然后在使用

 yum update

还是错误。

仔细看下错误：

http://download.fedoraproject.org/pub/fedora/linux/releases/17/Everything/x86_64/os/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found : http://download.fedoraproject.org/pub/fedora/linux/releases/17/Everything/x86_64/os/repodata/repomd.xml

就是源的配置问题嘛！

搜狐源配置文件地址： http://mirrors.sohu.com/help/fedora.html

按照说明还是不行，然后去官网和搜狐看了下，17下的文件夹已经空了 （查看http://ftp.iij.ad.jp/pub/linux/fedora/updates/17/），确实没法在更新了。

那我们只能想一个使用其他版本或者兼容版本的方式来更新了。

查看本机配置的yum源：yum repolist enabled

结果是可用的为０.

最后发现fedora17过了社区支持版本了，找到了一个历史版本的地方 http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/17/Fedora/x86_64/os/repodata/ 

这里有很多老版本的源。

下面是个后来可行的办法:

我是把/etc/yum.repos.d/下面出了fedora.repo 以外的源文件都删除了，然后把fedora.repo的base_url修改

http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/$releasever/Everything/$basearch/os/

[fedora]name=Fedora $releasever - $basearchfailovermethod=prioritybaseurl=http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/$releasever/Everything/$basearch/os/#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearchenabled=1metadata_expire=7dgpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch[fedora-debuginfo]name=Fedora $releasever - $basearch - Debugfailovermethod=prioritybaseurl=http:http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/$releasever/Everything/$basearch/debug/#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-debug-$releasever&arch=$basearchenabled=0metadata_expire=7dgpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch[fedora-source]name=Fedora $releasever - Sourcefailovermethod=prioritybaseurl=http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/$releasever/Everything/source/SRPMS/#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-source-$releasever&arch=$basearchenabled=0metadata_expire=7dgpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

然后执行 

yum clean metadatayum clean allyum update

最后查看是否可用

[root@Erya yum.repos.d]# yum repolist Loaded plugins: langpacks, presto, refresh-packagekitrepo id                                                                               repo name                                                                                        statusfedora                                                                                Fedora 17 - x86_64                                                                               27,033repolist: 27,033

这样yum又可以使用了。
