CentOS Multilib 版本冲突

Question 1

问题是是RHEL6/CentOS6 中没有libgcc.x86_64 0:4.8.2-8.el6软件包。EL6 的当前版本是 4.4.7-11，这是您当前安装的版本。

摆在你面前的任务是弄清楚为什么 yum 首先会找到这样的包。

首先，彻底清理 yum 缓存。可能有人无意中创建了这样的包，后来被拉了出来，但你的系统仍然有指向它的元数据。

yum clean all

第二，弄清楚 yum 在哪里想这样的包来自哪里。运行：

yum list all libgcc

在干净的 CentOS 6.6 系统上您应该得到以下输出：

Installed Packages
libgcc.x86_64                         4.4.7-11.el6                         @base
Available Packages
libgcc.i686                           4.4.7-11.el6                         base

如果您得到其他东西，则存储库将被识别，然后您可以禁用该存储库，联系其维护者，怀疑恶意活动等。

如果您获得相同的输出，那么您应该能够继续系统更新。

Question 2

我也有类似的问题。当我尝试更新 centos7 时，我得到以下结果：

Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:

  1. You have an upgrade for device-mapper-libs which is missing some
     dependency that another package requires. Yum is trying to
     solve this by installing an older version of device-mapper-libs of the
     different architecture. If you exclude the bad architecture
     yum will tell you what the root cause is (which package
     requires what). You can try redoing the upgrade with
     --exclude device-mapper-libs.otherarch ... this should give you an error
     message showing the root cause of the problem.

  2. You have multiple architectures of device-mapper-libs installed, but
     yum can only see an upgrade for one of those architectures.
     If you don't want/need both architectures anymore then you
     can remove the one with the missing update and everything
     will work.

  3. You have duplicate versions of device-mapper-libs installed already.
     You can use "yum check" to get yum show these errors.

...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).

Chronione wersje multilib: 7:device-mapper-libs-1.02.135-1.el7_3.2.x86_64 != 7:device-mapper-libs-1.02.135-1.el7_3.1.i686

就我而言，我遇到了问题device-mapper-libs。第一步，检查重复的包：

yum list --showduplicates device-mapper-libs-1.02.135-1.el7_3.1

updates  device-mapper-libs.x86_64

接下来删除无效的包：

yum erase device-mapper-libs.i686

现在执行更新/升级。成功了。
