解决Ubuntu的dpkg: error processing install-info问题

一、服务器安装软件是出现以下的错误信息：

$ sudo apt-get install nfs-common
Processing triggers for ureadahead (0.100.0-19.1) ...
Processing triggers for systemd (229-4ubuntu21.31) ...

二、具体步骤

1. 将info文件夹更名

# sudo mv /var/lib/dpkg/info/ /var/lib/dpkg/info_old/

2. 再新建一个新的info文件夹

# sudo mkdir /var/lib/dpkg/info/

3. 更新文件列表

# sudo apt-get update

4. 重新安装

# sudo apt-get -f install

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

# sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info_old/

6. 把自己新建的info文件夹删掉

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

7. 把info_old文件夹重新改回info

# sudo mv /var/lib/dpkg/info_old/ /var/lib/dpkg/info/

8. 输入上述命令之后，再执行 sudo apt-get update 就不会有问题了
