Fedora 20：“无法解析主机：download.fedoraproject.org”

我新安装了 Fedora 20，并且互联网连接（ping、网络浏览器）工作正常。但是，当我尝试时，yum update我收到以下错误消息：

failure: repodata/repomd.xml from download.fedoraproject.org_pub_fedora_linux_updates_testing_20_i386_: [Errno 256] No more mirrors to try.
http://download.fedoraproject.org/pub/fedora/linux/updates/testing/20/i386/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: download.fedoraproject.org"

附加信息：

$ cat /etc/issue
Fedora release 20 (Heisenbug)

$ ls /etc/yum.repos.d/

我也尝试过（也许有帮助）：

我怎样才能解决这个问题？

该网站现在似乎已关闭。

作为临时措施，您可以在文件中添加一个条目/etc/hosts：

137.226.34.42 download.fedoraproject.org

然后升级您的系统，注释掉上面的条目并重新启动，看看问题是否随着升级而消失。

137.226.34.42是ftp.halifax.rwth-aachen.de。
