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

在使用fedora17 系统的yum源的时候出现了例如以下错误：

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

參照网上的做法： （一般yum有变更都须要这两个操作）

yum clean all 

yum clean metadata

然后在使用

 yum update

还是错误。

细致看下错误：

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

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

那我们仅仅能想一个使用其它版本号或者兼容版本号的方式来更新了。

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过了社区支持版本号了，找到了一个历史版本号的地方 http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/17/Fedora/x86_64/os/repodata/

这里有非常多老版本号的源。

以下是个后来可行的办法:

我是把/etc/yum.repos.d/以下出了fedora.repo 以外的源文件都删除了。然后把fedora.repo的base_url改动

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

[fedora]
name=Fedora $releasever - $basearch
failovermethod=priority
baseurl=http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/$releasever/Everything/$basearch/os/
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch
enabled=1
metadata_expire=7d
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

[fedora-debuginfo]
name=Fedora $releasever - $basearch - Debug
failovermethod=priority
baseurl=http:http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/$releasever/Everything/$basearch/debug/
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-debug-$releasever&arch=$basearch
enabled=0
metadata_expire=7d
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

[fedora-source]
name=Fedora $releasever - Source
failovermethod=priority
baseurl=http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/$releasever/Everything/source/SRPMS/
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-source-$releasever&arch=$basearch
enabled=0
metadata_expire=7d
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

然后运行 

yum clean metadata
yum clean all
yum update

最后查看是否可用

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

这样yum又能够使用了。
