E: Sub-process /usr/bin/dpkg returned an error code (1)通过执行下面的命令可以解决该问题：
$ 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。
