我正在运行 Debian 9，vanilla 安装。
我的硬件是 HP Z230-SFF 工作站、Intel Core i7-4790、GPU Nvidia Quadro K620。
通常在启动时我会收到以下错误： tpm: tpm0 a error(7)occurred attempts to read a pcr value（我认为这与我的问题无关；但只是提及它，以防它以某种方式相关）我不知道）。
我的问题是在尝试安装 git 时：我在 Jessie 上看到过与此相同问题相关的帖子；然而，那里提到的解决方案都没有解决拉伸问题。我得到相同的依赖项错误：
我运行 Synaptic GUI，当我标记包 git 时，我得到以下信息：
git:
Depends: liberror-perl but it is not installable
Depends: git-man but it is not going to be installed
Depends: git-man but it is not going to be installed
Recommends: patch but it is not installable
