You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我该如何修复我的依赖关系以便一切都能正确更新？
答案1
看来您有一台 Centos 6 机器，但已为 Centos 7 配置了 Epel 存储库。这行不通。删除它并安装 Centos 6 Epel 存储库，位置如下：
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
确保您也卸载了从 Centos 7 Epel 存储库添加的所有内容。
那就可以了。
答案2
运行以下命令：
yum remove epel-release
然后运行：
yum update
这应该可以解决你的问题。
答案3
确实，我在 Centos 6 机器上错误地使用了 Centos 7 的 Epel 存储库。我尝试了上述解决方案，但它们只成功了一半。以下是最终对我有用的方法。
