我今天尝试在笔记本电脑上安装 Steam，但毫无意外，它坏了，需要进行调整，就像每次我在 Linux 上安装 Steam 一样。
在我尝试修复缺失的依赖项的过程中，我发现我彻底破坏了我的 apt-get 功能。
事情是这样的。
sudo apt-get install cowsay
它会弹出一条可爱但完全无用的消息：
Reading package lists... Done
Building dependency tree
Reading state information... Done
cowsay is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libllvm3.6:i386 : Depends: zlib1g:i386 (>= 1:1.2.0) but it is not going to
be installed
libpciaccess0:i386 : Depends: zlib1g:i386 (>= 1:1.2.3.3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
So I do the next logical step, the console is telling me to run:
sudo apt-get -f install
好吧，那就试试吧。不，我只是给你一种我正在工作的错觉，让你生气：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Correcting dependencies... Done
The following extra packages will be installed:
zlib1g:i386
The following NEW packages will be installed:
zlib1g:i386
0 upgraded, 1 newly installed, 0 to remove and 13 not upgraded.
6 not fully installed or removed.

E: Sub-process /usr/bin/dpkg returned an error code (1)
到目前为止，我觉得我已经尝试了所有方法。我按照一份相当冗长的指南尝试重新配置我的 dpkg、使用 apt-get clean 等等。重新启动对我没有任何作用。
我完全不知所措了。我只想重新安装 Linux，但我不想因为 Steam 破坏了我的 apt-get 而备份我所有的工作。

我刚刚修复了它。我所需要做的事情在这篇文章中概述了： 由于 libjackd 导致依赖关系中断
于是我去了/usr/share/doc，然后把zlib1g和zlib1g-dev都改名为.old背面的。这让我能够
apt-get -f install
现在一切看上去都很幸福。
