更新 CentOS 时，yum 崩溃了，给我留下了Error: rpmdb open failed.我厌倦了修复它这个答案这给我留下了工作和一些未完成的交易。
然后我唤起yum-complete-transaction并尝试，yum history undo last但后来失败了，所以我唤起yum check（输出如下）。后来我尝试使用 删除所有重复的包yum remove $(cat list)，其中“列表”是带有空格分隔的包列表的文件yum check。因此，我需要删除大量依赖项，包括受保护的软件包（systemd 和 yum）。
我不知道从现在起我应该走向何方。我应该提供一些额外的命令输出吗？
编辑： 我忘了提及系统没有使用新内核启动（很明显）。

Error: check all
答案1
好的，所以我不知道为什么我尝试删除那些损坏的软件包而不是重新安装它们，因此重新安装所有损坏的软件包的方式有点黑客：
yum reinstall $(yum check | awk 'NR!=1{print $1}' | tr '\n' ' ')
