CentOS - yum install - 失败：受保护的 Multilib 版本：发现问题 libselinux
CentOS - yum install - Fails: Protected Multilib versions: problems found libselinux
我有 CentOS 6.5
我正在尝试通过 yum 安装 git，但在安装先决条件包时出现错误。 我不需要，但它不会伤害 运行 使用 root 执行 sudo。
错误信息：
--> Finished Dependency Resolution
Error: 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 libselinux which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libselinux 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 libselinux.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libselinux installed, but
yum can only see an upgrade for one of those arcitectures.
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 libselinux 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).
Protected multilib versions: libselinux-2.0.94-5.3.el6_4.1.i686 != libselinux-2.0.94-5.8.el6.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Error Summary

我看到这个 post 为 CentOS 6 (x86_64) 安装额外的软件包 repo，但这没有帮助。使用这个，现在我遇到了第三个错误。
# wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

现在 yum repolist 显示额外的一行（对于额外的软件包 - CentOS）：
epel Extra Packages for Enterprise Linux 6 - x86_64 11,838
仍然，运行：
sudo yum -y install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker 仍然给我同样的错误（我首先提到在顶部）。

Puppetlabs.repo 对于这个 post 似乎是多余的，前 2 个 .repo 文件在我下载 + 安装额外的包 repo rpm 后安装在这里（如上面 post/link 中所列） ) 和 mycompany.redhat.repo 中的内容是：

我在 /etc/yum.repos.d/CentOS-Base.repo 或某个名称创建了一个文件（我让它有点通用所以它适用于任何 6.x 或 7 版本）。它适用于 6.5。如果您在 CentOS 7.x 上使用此文件时发现任何问题，那么您所需要的只是正确的 CentOS-Base.repo（CentOS 7.x 或任何 X.Y 版本的官方 .repo 文件) 并且 post 中出现的问题将得到解决。
例如：
/etc/yum.repos.d/CentOS-Base-Custom.repo 的内容

我现在需要的是在 Ansible 中使用模板模块（并将此文件设置在目标机器上的 /etc/yum.repos.d 文件夹中），一旦完成，上面的 pre-requisites将安装而不会出现任何错误，ansible 将安装我需要的所需（用户定义的 GIT 版本）。
这可能是因为架构之间的版本不匹配。查看它尝试更新的 32 位版本与 64 位版本有何不同。
先尝试更新安装的 64 位版本？
$sudo yum update libselinux.x86_64
$sudo yum update libselinux.i686
如果仍然失败，请确保您只安装了一个版本的软件并删除任何旧版本。
$sudo yum erase libselinux-2.0.94-5.8.el6.x86_64
对我有用的方法：
sudo package-cleanup --dupes
sudo package-cleanup --cleandupes
sudo package-cleanup --cleandupes --removenewestdupes
sudo yum update
如果 yum 更新仍然失败 - 继续如下操作：
使用 yum search 检查有问题的库的安装版本
例如：如果问题出在 libselinux
sudo yum list --showduplicates libselinux
在结果中，您可能会看到以 x86_64 或 i686 结尾的库版本
例如 ：
libselinux.i686
libselinux.x86_64
现在-我们需要找出要删除其中的哪一个，所以
我们 运行:
uname -a
如果我们在结果中看到（在左边的第 3 个参数上）：类似于：4.18.16-x86_64-myserver 那么我们是 保留 后缀为 x86_64 的库并用
后缀 i686
如果我们在第 3 个参数上看到 i686，那么我们 摆脱 x86_64 并保留 i686
所以，例如，如果我有 4.18.16-x86_64-myserver，我将去 运行:
sudo yum erase libselinux.i686
完成后 - 我们可以 运行 yum update 或 yum reinstall 我们要升级的库 ( libselinux)
我在 RHEL 7.7 上也遇到了同样的问题，我已经修复如下：
在 运行 #yum update 命令之后我遇到了以下错误：
采取的步骤：
#yum install yum-utils
#yum update kernel*
#package-cleanup --dupes
#package-cleanup --problems
然后我已经一个一个更新了这个包
#yum update audit
#yum update Network*
#yum update initscripts
#yum remove grub2-tools-minimal
#yum update grub2*
最后 运行
#yum 更新
效果很好。
如果其他方法对你的情况不起作用，你也可以尝试降级软件包，例如：
yum downgrade libxml2.x86_64
就我而言，我在使用 libxml2 的 Centos 7 上遇到了问题：
Protected multilib versions: libxml2-2.9.1-6.el7.4.i686 != libxml2-2.9.1-6.el7.5.x86_64
但实际上我只安装了1个libxml2包，也就是x86_64。在尝试使用 --setopt=protected_multilib=false 选项安装其他软件包时，我收到此消息
package libxml2-2.9.1-6.el7.5.x86_64 (which is newer than libxml2-2.9.1-6.el7.4.i686) is already installed
在那之后，我尝试降级软件包并且成功了。
我有 CentOS 6.5
我正在尝试通过 yum 安装 git，但在安装先决条件包时出现错误。 我不需要，但它不会伤害 运行 使用 root 执行 sudo。
错误信息：
--> Finished Dependency Resolution
Error: 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 libselinux which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libselinux 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 libselinux.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libselinux installed, but
yum can only see an upgrade for one of those arcitectures.
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 libselinux 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).
Protected multilib versions: libselinux-2.0.94-5.3.el6_4.1.i686 != libselinux-2.0.94-5.8.el6.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

--> Finished Dependency Resolution
Error: 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 libselinux which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libselinux 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 libselinux.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libselinux installed, but
yum can only see an upgrade for one of those arcitectures.
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 libselinux 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).
Protected multilib versions: libselinux-2.0.94-5.3.el6_4.1.i686 != libselinux-2.0.94-5.8.el6.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

我看到这个 post 为 CentOS 6 (x86_64) 安装额外的软件包 repo，但这没有帮助。使用这个，现在我遇到了第三个错误。

我在 /etc/yum.repos.d/CentOS-Base.repo 或某个名称创建了一个文件（我让它有点通用所以它适用于任何 6.x 或 7 版本）。它适用于 6.5。如果您在 CentOS 7.x 上使用此文件时发现任何问题，那么您所需要的只是正确的 CentOS-Base.repo（CentOS 7.x 或任何 X.Y 版本的官方 .repo 文件) 并且 post 中出现的问题将得到解决。
例如： /etc/yum.repos.d/CentOS-Base-Custom.repo 的内容 （PS：我将其命名为自定义，因为我没有使用硬编码版本 6，而是在 中使用了 $releasever 变量.repo 文件中的名称、镜像列表、baseurl、gpgkey 字段。

[root@server01 yum.repos.d]#
我现在需要的是在 Ansible 中使用模板模块（并将此文件设置在目标机器上的 /etc/yum.repos.d 文件夹中），一旦完成，上面的 pre-requisites将安装而不会出现任何错误，ansible 将安装我需要的所需（用户定义的 GIT 版本）。
这可能是因为架构之间的版本不匹配。查看它尝试更新的 32 位版本与 64 位版本有何不同。
先尝试更新安装的 64 位版本？
$sudo yum update libselinux.x86_64
$sudo yum update libselinux.i686
如果仍然失败，请确保您只安装了一个版本的软件并删除任何旧版本。
$sudo yum erase libselinux-2.0.94-5.8.el6.x86_64
对我有用的方法：
sudo package-cleanup --dupes
sudo package-cleanup --cleandupes
sudo package-cleanup --cleandupes --removenewestdupes
sudo yum update
如果 yum 更新仍然失败 - 继续如下操作：
使用 yum search 检查有问题的库的安装版本 例如：如果问题出在 libselinux
sudo yum list --showduplicates libselinux
在结果中，您可能会看到以 x86_64 或 i686 结尾的库版本 例如 ： libselinux.i686 libselinux.x86_64
现在-我们需要找出要删除其中的哪一个，所以 我们 运行:
uname -a
如果我们在结果中看到（在左边的第 3 个参数上）：类似于：4.18.16-x86_64-myserver 那么我们是 保留 后缀为 x86_64 的库并用 后缀 i686
如果我们在第 3 个参数上看到 i686，那么我们 摆脱 x86_64 并保留 i686
所以，例如，如果我有 4.18.16-x86_64-myserver，我将去 运行:
sudo yum erase libselinux.i686
完成后 - 我们可以 运行 yum update 或 yum reinstall 我们要升级的库 ( libselinux)
我在 RHEL 7.7 上也遇到了同样的问题，我已经修复如下：
在 运行 #yum update 命令之后我遇到了以下错误：
采取的步骤：
#yum install yum-utils
#yum update kernel*
#package-cleanup --dupes
#package-cleanup --problems
然后我已经一个一个更新了这个包
#yum update audit
#yum update Network*
#yum update initscripts
#yum remove grub2-tools-minimal
#yum update grub2*
最后 运行 #yum 更新
效果很好。
如果其他方法对你的情况不起作用，你也可以尝试降级软件包，例如：
yum downgrade libxml2.x86_64
就我而言，我在使用 libxml2 的 Centos 7 上遇到了问题：
Protected multilib versions: libxml2-2.9.1-6.el7.4.i686 != libxml2-2.9.1-6.el7.5.x86_64
但实际上我只安装了1个libxml2包，也就是x86_64。在尝试使用 --setopt=protected_multilib=false 选项安装其他软件包时，我收到此消息
package libxml2-2.9.1-6.el7.5.x86_64 (which is newer than libxml2-2.9.1-6.el7.4.i686) is already installed
在那之后，我尝试降级软件包并且成功了。
