dpkg: warning: files list file for package 'xxxx' missing; assuming package has no files currently installed

2021-06-18，找到最佳的解决办法：

新建 dpkg-warning-fix.sh 文件，编辑内容：

#!/bin/bash
set -e


# Clean out /var/cache/apt/archives
apt-get clean
# Fill it with all the .debs we need
apt-get --reinstall -dy install $(dpkg --get-selections | grep '[[:space:]]install' | cut -f1)


DIR=$(mktemp -d -t info-XXXXXX)
for deb in /var/cache/apt/archives/*.deb
do
    # Move to working directory
    cd "$DIR"
    # Create DEBIAN directory
    mkdir -p DEBIAN
    # Extract control files
    dpkg-deb -e "$deb"
    # Extract file list, fixing up the leading ./ and turning / into /.
    dpkg-deb -c "$deb" | awk '{print $NF}' | cut -c2- | sed -e 's/^\/$/\/./' > DEBIAN/list
    # Figure out binary package name
    DEB=$(basename "$deb" | cut -d_ -f1)
    # Copy each control file into place
    cd DEBIAN
    for file in *
    do
        cp -a "$file" /var/lib/dpkg/info/"$DEB"."$file"
    done
    # Clean up
    cd ..
    rm -rf DEBIAN
done
rmdir "$DIR"

原理是重新下载所有安装过的软件包，然后从中提取文件列表信息复制到info文件夹里。（所以请在网速较好的时候使用）

sudo ./dpkg-warning-fix.sh

经验不足，按网上的教程操作，把 /var/lib/dpkg/info/ 的文件删除了，之后安装软件就会频繁出现如下警告：

解决办法：

新建 dpkg-warning.txt 文件,并把上述提示全部拷贝到 该文件中：

vi dpkg-warning.txt

新建 dpkg-warning-fix.sh 文件，编辑内容：

#!/bin/bash

for package in $(cat dpkg-warning.txt | grep "dpkg: warning: files list file for package " | grep -Po "'[^']*'" | sed "s/'//g")；
do
  apt install --reinstall "$package";
done

chmod 777 dpkg-warning-fix.sh

./dpkg-warning-fix.sh
