Dependencies CentOS-yum安装-失败：受保护的多库版本：在libselinux中发现问题

我有CentOS 6.5

我正试图通过yum导入所有的git，但在安装必备软件包时出错。我不需要，但用root运行sudo不会有任何伤害

错误消息：

--> 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:  Multilib version problems found. This often means that the root

       pointing out that there is a problem. Eg.:

         1. You have an upgrade for libselinux which is missing some

            --exclude libselinux.otherarch ... this should give you an error

         2. You have multiple architectures of libselinux installed, but

            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

我看到这一点是为了安装CentOS 6（x86_64）的额外软件包repo，但这没有帮助。使用这个，现在我得到了第三个错误

# wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

现在yum-repolist显示一个额外的行（对于额外的包-CentOS）：

不过，跑步： 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（我在顶部提到的第一个错误）

/etc/yum.repos.d包含-- #pwd；ls-l

Puppetlabs.repo对于这篇文章来说似乎是多余的，在我下载并安装了额外的包repo rpm（如上面的文章/链接所列）之后，这里安装了第一个2.repo文件，mycompany.redhat.repo中的内容如下：

[release.update]

我在/etc/yum.repos.d/CentOS Base.repo或其他名称处创建了一个文件（我将它做了一些通用性，以便它可以用于任何6.x或7版本）。它在6.5上起作用。如果您在CentOS 7.x中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），帖子中出现的问题将得到解决

例如： 目录/etc/yum.repos.d/CentOS Base Custom.repo （PS：我将其命名为custom，因为我没有使用硬编码版本6，而是在.repo文件中的名称、镜像列表、baseurl、gpgkey字段中使用了$releasever变量

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

我现在只需要在Ansible中使用模板模块（并在目标计算机上的/etc/yum.repos.d文件夹中设置此文件），完成后，将安装上述前提条件而不会出现任何错误，Ansible将安装所需的（用户定义的GIT版本）这是我需要的。

这可能是因为架构之间的版本不匹配。请查看它试图更新的32位版本与64位版本如何不同

是否先尝试更新已安装的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

---

对我有效的方法是：

sudo包清理--重复

sudo包清理--清除重复

sudo包清理--清除重复--移除重复

sudoyum更新

如果yum更新仍然失败-请按如下方式继续：

使用yum-search检查有问题库的安装版本 例如：如果问题是libselinux

sudoyum列表--显示重复项

在结果中，您可能会看到库版本以x86_64或i686结尾 例如： libselinux.i686 libselinux.x86_64

现在-我们需要找出其中哪一个要扔掉，所以 我们经营：

联阿援助团

如果我们在结果中看到（在左边的第三个参数上）：类似于：4.18.16-x86_64-myserver，那么我们将保留带有后缀x86_64的库，并使用 后缀i686

如果我们在第3个参数上看到i686，那么我们将摆脱x86_64并保持i686

例如，如果我有4.18.16-x86_64-myserver，我将运行：

sudoyum-eraselibselinux.i686

---

完成此操作后-我们可以在要升级的库（libselinux）上运行yum update或yum reinstall，

我在RHEL 7.7上也遇到了同样的问题，我已将其修复如下：

运行#yum update命令后，我发现以下错误：

采取的步骤：

#yum install yum-utils

#yum update kernel*

#package-cleanup --dupes

#package-cleanup --problems

然后我一个一个地更新了这个包

#yum update audit

#yum update Network*

#yum update initscripts
#yum remove grub2-tools-minimal

#yum update grub2*

终于跑了 #yum更新

---

它工作得非常好。

您能在这里改进一下格式吗？代码需要缩进4个空格，以便进行代码标记

#yum update audit

#yum update Network*

#yum update initscripts
#yum remove grub2-tools-minimal

#yum update grub2*
