问题：dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

 1. 问题：Ubuntu安装软件的过程中出现依赖项的问题

 “E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).” 

按照指示执行如下两条命令都没有解决问题。

sudo apt-get -f install
sudo apt-get --fix-broken install

反而又出现“dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)”的问题

Preparing to unpack .../ros-melodic-moveit-core_0.10.8-0bionic.20181227.040044_amd64.deb ...

最终解决办法：

sudo apt-get autoremove ros-melodic-moveie-experimental(总之就是出错的几个全都autoremove掉)
sudo apt-get -f install

后记：这个问题的起源是在ubuntu18.04下安装ros时出现的遗留问题，因为对一般的软件安装没有影响，所以就弃置不管，但是今天安装teamviewer时遇到了依赖项问题，执行-f install 的时候报错不能执行，所以才痛下决心解决这个问题。最初多方尝试无果，准备重新安装ros，没想到purge命令居然不能执行，足见这个问题之霸道，而我对系统了解之浅薄。
