ROS indigo Ubuntu14.04 安装问题

错误信息：Unpacking ros-indigo-desktop-full (1.1.6-0trusty-20181006-135515-0800) ...
Errors were encountered while processing:
 /var/cache/apt/archives/python-rosdistro-modules_0.7.0-1_all.deb
 /var/cache/apt/archives/python-rosdistro_0.7.0-100_all.deb

导致这种问题一般是第一次安装，中途打断安装导致

解决方法：卸载ros

sudo apt-get remove ros-jade-desktop-full
sudo apt-get remove ros-*  #但是不确定会不会删除其它不必要的包。

更新dpkg

sudo apt-get install dpkg

接下来重新安装就可以了
