如何修复RHEL 5.3框上的yum错误

尝试在RHEL 5.3 linux机器上安装任何软件包时出现错误。我以前使用yum安装了mc（midnight commander），但最近它开始失败。

我该如何解决？

谢谢，

我在下面插入了会话的日志。

除非是网络问题（尝试在浏览器中打开URL），否则无法真正解决该问题。传递--disablerepo=adobe-linux-i386给yum暂时禁用存储库。

以下命令行可能会有所帮助：

yum clean all && yum makecache && yum update

转到/eyc/yum.repos.d，然后检查您那里没有重复项（输出显示该方向的投诉）。查看不同的存储库，并确保您确实需要它们（“安装的yum列表”会告诉您每个软件包的来源）。
