Yum 无法在 Amazon 实例上运行

Yum 在我的一些 amazon 实例上失败了，我尝试跟进 amazon 人员，但尚未修复。以下是错误、python 和 yum 版本信息：

答案1

问题在于 SSLwrap 在 python 2.7 及更高版本中被删除。要纠正此问题，一个简单的解决方案是让 yum 使用 python2.6

vim /usr/bin/yum

将其中的 shebang 更改为 python2.6

答案2

该文件好像有问题/usr/local/lib/python2.7/ssl.py。

您能否从故障机器和正常运行的机器发布此文件的 md5sum？您还可以检查 python 版本是否相同吗？
