抱歉，我的问题太愚蠢了。也许有人能解释一下我的问题出在哪里？我根本没碰过系统（新安装的 14.04）。谢谢。
答案1
运行sudo apt-get install libdpkg-perl=1.17.5ubuntu5降级libdpkg-perl。
您以某种方式安装了比存储库中版本更新的软件包版本，这导致其他软件包出现问题。
答案2
尝试代码：
sudo apt-get update
更新你的包裹清单。
然后代码：
sudo apt-get autoclean
清理所有不完整的包。
然后代码：
sudo apt-get clean
清理 apt 缓存。
然后代码：
sudo apt-get autoremove
将清除任何不需要的依赖项。
如果在执行此操作时您可以识别损坏的包装，此代码将非常有力地将其删除。
代码：
sudo dpkg --remove -force --force-remove-reinstreq <package name>
当然是将包名称更改为真实名称。
然后，返回到您的 build-essential 安装
代码：
sudo apt-get install dpkg-dev
sudo apt-get install build-essential
看看这是否适合你。
答案3
对我来说，我重新安装了
libdpkg-perl
并且成功了。如果您使用 synaptic，您可以允许 synaptic 降级此软件包
