服务器之前安装过 redis-server，因已经将服务迁移至 Kubernetes，因此只需要安装 redis-cli 客户端即可。
执行包管理命令进行安装，结果执行安装报错：
sudo apt install redis-tools

dpkg: unrecoverable fatal error, aborting:
unknown system user 'redis' in statoverride file; the system user got removed
before the override, which is most probably a packaging bug, to recover you
can remove the override manually with dpkg-statoverride
E: Sub-process /usr/bin/dpkg returned an error code (2)异常
可以看到报错信息如下：
dpkg: unrecoverable fatal error, aborting:
unknown system user 'redis' in statoverride file; the system user got removed
before the override, which is most probably a packaging bug, to recover you
can remove the override manually with dpkg-statoverridedpkg-statoverride 是 Debian/Ubuntu 系统中用于管理文件权限覆盖的工具，它允许用户手动修改文件或目录的权限和所有者，并且这些更改在系统更新时会被保留，因为用户操作的原因导致部分权限改动残留，和需要安装的包内容存在冲突，需要先处理这部分异常。
解决
使用命令查询所有存在的权限改动记录：
## 此命令查询的文件为 '/var/lib/dpkg/statoverride'
## 不过还是推荐使用命令执行标准操作，而不是直接编辑文件内容
sudo dpkg-statoverride --list输出结果为：
redis redis 640 /etc/redis/redis.conf找到其中涉及 redis 的行和其涉及的文件，执行命令：
sudo dpkg-statoverride --remove /etc/redis/redis.conf附录
