我在运行亚马逊AMI的EC2上有一个实例。从本周开始，由于依赖解析问题，我无法完成yum更新：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我真的不认为删除util-linux-ng来解决依赖关系会是一个很好的解决方案，因为我在该软件包中看到了很多关键工具。有没有人有一个好的解决方案？提前谢谢。
答案 0 :(得分：3)
yum clean all
和
yum update
为我解决了这个问题。
yum clean all将删除yum缓存的所有内容，确保在运行命令之前不依赖任何缓存的数据。

看起来你需要等待亚马逊更新到 util-linux-ng-2.17.2-13.17.amzn1.i686
与此同时，您可以遵循以下建议：
You could try using --skip-broken to work around the problem
通过运行：
yum update --skip-broken
更新其他所有内容。
