apt保留缓存deb包，安装后不删除源文件安装包

使用apt安装包后，缓存目录下的包不被自动删除

按照如下修改，先修改20archive，在增加自定义文件，添加两条命令即可

apt 会按文件名中​​数字部分的升序​​依次加载配置文件（即数字越小，文件越早被加载），所以自定义99开头会覆盖前面的命令

 

root@ceph-node1:/etc/apt/apt.conf.d# cat 20archive 
APT::Archives::MaxAge "0";
APT::Archives::MinAge "0";
APT::Archives::MaxSize "0";

 

Binary::apt::APT::Keep-Downloaded-Packages "true";
APT::Keep-Downloaded-Packages "false";
