【中文标题】Dnf 删除了 mariadb-config 和 mariadb-common 的许多依赖项【英文标题】：Dnf removes many dependencies along mariadb-config and mariadb-common 【发布时间】：2018-06-03 15:48:34 【问题描述】：在 Fedora 26 上工作。已安装 mariadb 10.1.26，但我需要 10.2.2 上可用的一些功能。
要从 MariaDB 存储库安装 MariaDB-server 10.2，似乎有必要删除 mariadb-config 和 mariadb-common，因为某些文件存在冲突：
# dnf install MariaDB-server

如果我尝试删除相关软件包 mariadb-config 和 mariadb-common，DNF 需要删除令人印象深刻的不相关软件包列表，例如 shotcut、blender、mplayer。示例：

似乎不是...如何安装MariaDB-server（caps = 10.2）而不删除不相关的包（我实际上想保留而不是删除/重新安装）？
【问题讨论】：
yum remove MariaDB-server MariaDB-client，然后再试一次。
正如我所说（这是我的问题的重点），它想要删除不相关的包。我不想删除那些包（问题中提供的列表摘录）。
祝你好运，欢迎来到linux xD
【参考方案1】：
终于成功了：
使用 yumex (GUI) 删除了 mariadb-* 使用 dnf (CLI) 删除了 mariadb-server 使用 dnf 安装 MariaDB-* (10.2)由于未知原因，Yumex 没有删除不相关的软件包，而 dnf 会删除。
【讨论】：
原因很简单，yumex-dnf 不会删除“弱依赖”，也不会删除“级联依赖”，但 dnf 会。有关“弱依赖”的文档，请查看：fedoraproject.org/wiki/PackagingDrafts/WeakDependencies 感谢您的评论和链接。但是，例如，Blender 绝对与 mariadb-config 无关：mariadb-config 既不是弱依赖也不是级联依赖，它根本不是依赖...以上是关于Dnf 删除了 mariadb-config 和 mariadb-common 的许多依赖项的主要内容，如果未能解决你的问题，请参考以下文章
