我有一个简单的剧本，试图在我的服务器中安装本地下载的Debian包。这个剧本在localhost上运行，并在同一系统中安装Debian包。但是这个剧本给出了一个错误"依赖性是不可满足的对于一些包，即使很难，依赖性包在本地存储库中也是可用的
我可以使用apt-get install --download-only package_name在本地存储库中下载特定包所需的所有依赖项
但在我的剧本中，我应该有一个机制来首先安装依赖项，而不是安装实际的包。这个任务应该是动态的，剧本应该自己解决任何包安装的依赖关系。
当包依赖于另一个包时，剧本如何动态解析
探索的一些选项：
Using ordered indexed_items, using gdebi.. Looking for efficient Logic.
本地存储库有包->它可以根据需求增长：
wireshark_3.0.5-1_amd64.deb wireshark-qt_3.0.5-1_amd64.deb
这里，wireshark_3.0.5-1_amd64.deb与wireshark-qt_3.0.5-1_amd64.deb有依赖关系。

首先在远程服务器中设置本地存储库，并在远程服务器上使用apt-get install --download-only package_name下载安装包。修改本地系统/etc/apt/sources.list以指向本地存储库包。
当ansible脚本尝试使用apt-get-y-install进行安装时，它将连接到本地存储库并获取包并解析依赖关系。
