一、服务器安装软件是出现以下的错误信息：
www@TinywanAliYun:~$ sudo apt-get install letsencrypt Reading package lists... Done Building dependency tree Reading state information... Done letsencrypt is already the newest version (0.17.0-2+ubuntu16.04.1+certbot+1). 0 upgraded, 0 newly installed, 0 to remove and 52 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Do you want to continue?

二、具体步骤
1、将info文件夹更名
命令如下：www@TinywanAliYun:~# mv /var/lib/dpkg/info/ /var/lib/dpkg/info_old/
2、再新建一个新的info文件夹
命令如下：www@TinywanAliYun:~# mkdir /var/lib/dpkg/info/
3、更新文件列表：apt-get update
命令如下：www@TinywanAliYun:~# apt-get update
信息如下：
www@TinywanAliYun:~$ sudo apt update [sudo] password for www: Hit:1 http://mirrors.cloud.aliyuncs.com/ubuntu xenial InRelease Hit:2 http://mirrors.cloud.aliyuncs.com/ubuntu xenial-updates InRelease Hit:3 http://mirrors.cloud.aliyuncs.com/ubuntu xenial-security InRelease Hit:4 http://ppa.launchpad.net/certbot/certbot/ubuntu xenial InRelease
4、重新安装
命令如下：www@TinywanAliYun:~# apt-get -f install
信息如下：
www@TinywanAliYun:~$ sudo apt-get -f install Reading package lists... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 52 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Setting up php7.0-mysql (7.0.22-0ubuntu0.16.04.1) ...
5、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
命令如下：www@TinywanAliYunu:~# mv /var/lib/dpkg/info/* /var/lib/dpkg/info_old/
6、把自己新建的info文件夹删掉
命令如下：www@TinywanAliYun:~# rm -rf /var/lib/dpkg/info
7、把info_old文件夹重新改回info
命令如下：www@TinywanAliYun:~# mv /var/lib/dpkg/info_old/ /var/lib/dpkg/info/
8、输入上述命令之后。
在执行 sudo apt-get update 就不会有问题了
9、继续到第一步的安装信息
www@TinywanAliYun:~$ sudo apt-get install letsencrypt Reading package lists... Done Building dependency tree Reading state information... Done letsencrypt is already the newest version (0.17.0-2+ubuntu16.04.1+certbot+1). 0 upgraded, 0 newly installed, 0 to remove and 52 not upgraded.
10、安装结束
