ubuntu好久没有使用了，使用apt-get install 安装软件，会出现很多错误
dpkg: warning: files list file for package 'mokutil' missing; assuming package has no files currently installed
dpkg: warning: files list file for package 'libquadmath0:amd64' missing; assuming package has no files currently installed
dpkg: warning: files list file for package 'python-apt-common' missing; assuming package has no files currently installed
dpkg: warning: files list file for package 'zerofree' missing; assuming package has no files currently installed

解决办法，使用 apt-get install --reinstall "package_name" -y 进行重新安装，如果列表太多，一个一个的手动安装太慢，可以使用脚本方式。
将所有的警告复制到文件 warning.txt 中；
编写如下脚本，命名为 auto_reinstall.sh
#!/bin/bash
for package in $(cat warning.txt | grep "warning: files list file for package '" | grep -Po "'[^']*'" | sed "s/'//g");
do
apt-get install --reinstall "$package" -y;
done
chmod a+x auto_reinstall.sh
sudo ./auto_reinstall.sh
执行完成后，如果报如下错误
dpkg: error processing package ******** (--configure)
使用如下命令来解决
sudo mv /var/lib/dpkg/info /var/lib/dpkg/info_old
sudo mkdir /var/lib/dpkg/info
sudo apt-get update
sudo 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
sudo mv /var/lib/dpkg/info_old /var/lib/dpkg/info
