Yum 安装损坏了 Redhat Ubi8 上的 lib

我正在开发 Redhat Ubi8-minimal 容器。我的目标是从文件安装 .rpm 及其依赖项。Ubi8-minimal 仅提供microdnf无法安装本地 .rpm 的版本。因此，我yum使用可以microdnf install yum顺利安装的版本进行了安装。在输出中，它显示libmodulemd正在更新：

Updating: libmodulemd;2.13.0-2.fc34;x86_64;Clients_Fedora_34_Fedora_34_Updates

但第一次调用时yum我得到：

[root@7fc9c0e586b1]# yum --version
Traceback (most recent call last):
  File "/usr/bin/yum", line 57, in <module>
    from dnf.cli import main
  File "/usr/lib/python3.9/site-packages/dnf/__init__.py", line 30, in <module>
    import dnf.base
  File "/usr/lib/python3.9/site-packages/dnf/base.py", line 29, in <module>
    import libdnf.transaction
  File "/usr/lib64/python3.9/site-packages/libdnf/__init__.py", line 12, in <module>
    from . import conf
  File "/usr/lib64/python3.9/site-packages/libdnf/conf.py", line 13, in <module>
    from . import _conf
ImportError: /lib64/libmodulemd.so.2: undefined symbol: g_ptr_array_extend_and_steal

此后microdnf也出现此问题并且无法再使用：

[root@7fc9c0e586b1]# microdnf --version
microdnf: symbol lookup error: /lib64/libmodulemd.so.2: undefined symbol: g_ptr_array_extend_and_steal

所以我无法再管理任何包和安装。

我该如何修复这个问题并让 yum 在 Ubi8 上运行？

这也是目录中唯一的 .repo 文件。我没有主动启用任何其他 repo。

这是命令的输出microdnf repolist --enabled。

这让我很困惑，因为它与的内容不匹配ubi.repo。

当任何 dnf 命令导致未定义符号时，您的包管理器就严重损坏了。fc34 标签表示基于 Fedora 34 的更新，这不适用于基于 el8 的发行版。在此处了解使用 Fedora 存储库的内容。

查看文档以获取有关如何在容器上运行完整 dnf 命令的提示。RHEL 8 构建容器利用 yum 的安装到 chroot 功能来执行此操作，即使使用微型容器也是如此。从主机：

yum install \
    --installroot $micromount \
    --releasever 8 \
    --setopt install_weak_deps=false \
    --nodocs -y \
    httpd

$micromount已安装的容器根文件系统在哪里，--releasever 8是 el 版本的 continer，httpd是您要安装的包。还可以修复您的 dnf 安装，可能使用 yum reinstall libmodulemd microdnf

答案2

感谢以下人士的提示约翰·马霍瓦尔德指向 fc34 repos 参与，一个解决方法是在安装时排除 Fedora repos yum：

microdnf install --disablerepo="Clients_*" yum

这将导致yum安装成功：

[root@4f6b589029d5]# yum --version

首先，这样做的必要性似乎是容器与subscription-manager主机系统的交互，它将订阅信息投射到正在运行的容器中。除了其他用户的提及和我自己的经验外，我还没有找到关于此的任何主要文档。
