我遇到了错误，我认为使用 coreutils，yum 不会更新。这是我在运行时看到的精简输出yum update：

There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them.
The program yum-complete-transaction is found in the yum-utils package.

You could try using --skip-broken to work around the problem

我有另一台服务器（几乎）与此相同（它们是负载平衡的并且从同一个图像工作）并且没有遇到同样的问题。可能是什么问题，我应该如何最好地进行？
更新：
我也运行yum-complete-transaction失败并说它已重命名事务文件。它仍然说有一个不完整的交易，但现在当我运行它时会发生这种情况：
[root@nico ~]# yum-complete-transaction

... and this:

然后它突然停在这Killed条线上。
我尝试yum update --skip-broken下一步运行：
[root@nico ~]# yum update --skip-broken

更新 2：
我也跑了yum clean all，在那里也遇到了一些问题。我找到了一些删除__db*文件并重试的建议：
[root@nico ~]# yum clean all

更新 3：
跑的时候尾/var/log/messages了，看到很多输出yum-complete-transaction，最后两行是：
Nov 14 08:19:47 nico kernel: Out of memory: Kill process 30995 (yum-complete-tr) score 149 or sacrifice child
Nov 14 08:19:47 nico kernel: Killed process 30995, UID 0, (yum-complete-tr) total-vm:641952kB, anon-rss:181420kB, file-rss:4kB
所以大概这表明它与记忆有关。如果是这样，这是需要更多 RAM 的情况，还是我需要调查另一个问题？
yum死亡的通常原因Killed是系统内存不足。从您的日志看来，您有一个 Amazon t1.micro 实例，或者类似大小的实例，并且没有任何交换空间。这种有限的内存量通常不足以完成大量的软件包安装/更新。
要解决此问题，请执行以下任一操作：
关闭正在运行的服务，直到您有足够的内存来完成 yum 事务。
或者...
向您的实例添加交换文件或交换临时存储。
然后您应该能够完成您的 yum 交易。
最后，要清除以前失败更新中的软件包问题，请尝试
在执行任何其他更新之前。
类似的问题 - 和我的修复。我的内存也有问题，所以不得不升级VPS的内存。然后我做了一个 yum 更新——当然得到了上面的错误。所以查看了失败，并注意到发生了什么是 Yum 安装（嗯，开始安装）最新的 coreutils - 版本 37，而我仍然有 31 位。所以首先，删除版本 37，然后清理然后运行 yum update再次。
这导致“31”版本可以干净地“更新”。请看下面的作品：
运行
yum remove coreutils-libs-8.4-37.el6.x86_64：清理使用
yum clean all：做包列表刷新
yum update：-苏普。
试试
you update --skip-broken这会跳过损坏的包（你可以稍后处理它们），yum clean all在做任何事情之前运行可能是个好主意。过滤掉您引用的无关信息，并且
yum已经尝试帮助您：你已经试过了吗？
试一试
yum 降级包名
不知道为什么，但它更新了，或者至少它为我做了 tcpdump 包。从版本 tcpdump-4.5.1-2.el7.x86_64 到 tcpdump-4.7.4-1_ESG_ring.x86_64 这正是我想要的。
