我在 Fedora 16 上使用 yum 执行任何操作时遇到问题。以下是我得到的输出：
[user@mycomputer yum-3.4.3]$ sudo yum update

有人对如何解决这个问题有任何想法吗？
答案1
repomd.xml这不是您的（存储库元数据）的损坏。我在这里看到两个可能的问题：
- 您的代理服务器有一份陈旧的部分检索副本，或者只是拒绝提供一份好的副本。
- 错误的副本被放置到存储库主服务器上，然后所有镜像都将其拉出（我曾经看到过它）。无论如何，在我写响应时，第一个选择的镜像返回了一个有效文件。
你的fedora.repo文件没问题。
答案2
yum.conf我通过在我的文件中添加最初丢失的代理标签来使其工作。
答案3
打开 yum.conf
vi /etc/yum.conf在最后添加“代理”标签
proxy=http://XXXX.XXX.XXXX.XXX:XXXX
保存并关闭。这应该有效。
答案4
用这个：
# sudo yum clean all
# sudo yum update
