pika:~$ping 192.168.31.191
PING 192.168.31.191 (192.168.31.191) 56(84) bytes of data.
From 192.168.31.98 icmp_seq=1 Destination Host Unreachable
说明不在同一局域网内，虽然ip前3位相同！！！
换个wifi试试就可以了。
或者No route to host
解决方案是：关闭防火墙
service iptables stop

解决方案：
$ sudo mv /var/lib/dpkg/info /var/lib/dpkg/info_old //现将info文件夹更名
$ sudo mkdir /var/lib/dpkg/info //再新建一个新的info文件夹
$ sudo apt-get update
apt-get -f install
$ sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info_old//执行完上一步操作后会在新的info文件夹下生成一些文件，现将这些文件全部移到info_old文件夹下
$ sudo rm -rf /var/lib/dpkg/info //把自己新建的info文件夹删掉
$ sudo mv /var/lib/dpkg/info_old /var/lib/dpkg/info //把以前的info文件夹重新改回名字
