解决方法：

现将info文件夹更名

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

新建一个新的info文件夹

sudo mkdir /var/lib/dpkg/info

安装修复

sudo apt-get update
sudo apt-get install -f 

执行完上一步操作后，在info文件夹下生成一些文件，现将这些文件全部移到info.bk文件夹下

sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info.bk

把自己新建的info文件夹删掉

sudo rm -rf /var/lib/dpkg/info

恢复原有info文件夹，修改名字

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