ps: 改过 /var/lib/dpkg/info目录，没用，如下：

#先备份原来的，然后重新新建

sudo mv /var/lib/dpkg/info /var/lib/dpkg/info.bak //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

#不用解释了吧，修复安装

apt-get -f install xxx
sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info.bak

#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.bak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.bak /var/lib/dpkg/info //把以前的info文件夹重新改回名字
