在几个月 (> 6) 没有软件升级后，我登录到运行的 EC2 实例：
Linux version 2.6.32-358.23.2.el6.x86_64 (mockbuild@x86-022.build.eng.bos.redhat.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Sat Sep 14 05:32:37 EDT 2013
然后尝试执行通常的 yum-update：
# yum update
好吧，失败了，错误如下：

You could try using --skip-broken to work around the problem
** Found 143 pre-existing rpmdb problem(s), 'yum check' output follows:
在阅读了几篇文章后，我尝试了几件事来纠正这个问题：
yum clean all，然后yum update。rpmdb --rebuilddb，然package-cleanup --dupes，然package-cleanup --cleandupes。yum-complete-transaction等在所有情况下，我最终都在同一个地方。一篇文章建议我可能有 glibc 的冲突包。无论如何，我无法说出发生了什么。我应该重新实例化我的 EC2，还是有人有解决方案？
谢谢！
为我的 RHEL 6.4 (Fedora 12+) 环境解决 yum-updates 非常耗时，但最终成功。我想分享我做了什么，还有什么可以做得更好。
package-clean --dupes也是一样的。另一个有用的命令是，它通过前缀或通用包名称识别重复的包。rpm -qa package-namecoreutilsand coreutils-lib，或多或少遵循以下命令序列： (i) rpm -e --nodeps coreutils、 (ii) rpm -e --nodeps coreutils-lib、 (iii)updatedb和 (iv) yum clean all。注意：coreutils通常不建议删除，因为它会使许多其他命令无法运行。coreutils和coreutils-lib：yum install coreutils coreutils-libpackage-cleanup --cleandupes，我遇到了内存分配问题以及核心转储问题。我从而手动不得不移除每个重复包，使用前面提到的命令： rpm -e --nodeps package-name。updatedb、 (ii)yum clean all和 (iii) yum update。在所有这一切之后，事情现在起作用了。
建议：如果有像“yum self-resolve”这样的命令会很有帮助。它将对要删除的包和要保留的包执行最佳猜测策略，以便使陈旧的环境保持最新。如果这样的命令已经存在，请告诉我。
为我工作 sudo package-cleanup --cleandupes
我也是，我曾经无法更新我的系统（package-cleanup或者yum clean all也没有帮助）。两天后我就能够了。
如果您尚未将非官方存储库添加到您的发行版中，则可能是您的镜像的问题，或者只是存储库中的错误/不完整的软件包更新（可能很快就会修复）。
