安装python apt软件包时软件包损坏

我想在debian（挤压）服务器中安装

python apt

包：

但我得到了以下错误：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

 python-apt : Depends: libapt-inst1.2
              Depends: libapt-pkg4.10
E: Unable to correct problems, you have held broken packages.

---

我不知道如何更正此错误：（

将libapt-inst1.2和libapt-pkg4.10安装为Linux软件包？是的，这些都是Linux软件包。我无法解决依赖性问题。为什么您不能用Linux的安装工具安装这些软件包？当我键入以下内容时：

apt get Install libapt-inst1.2

我得到以下错误：

apt-utils:dependens:libapt-pkg4.10

以及何时我想安装

libapt-pkg4.10

我收到以下错误：

E:Package'libapt-pkg4.10'没有安装候选程序

请检查！
