报错原因：usr目录下文件出错，重新配置即可
依次输入以下命令可以解决问题：

$ sudo mv /var/lib/dpkg/info/ /var/lib/dpkg/info_old/
$ sudo mkdir /var/lib/dpkg/info/
$ sudo apt-get update    
$ sudo apt-get -f install
$ sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info_old/
$ sudo rm -rf /var/lib/dpkg/info
$ sudo mv /var/lib/dpkg/info_old/ /var/lib/dpkg/info/

输入上述命令之后，在执行 sudo apt-get update 和 sudo apt-get upgrade 就不会有问题了 重新下载需要的包都没问题了
