apt download 离线下载所有依赖

局域网很多时候因为依赖不足，无法安装软件。可以采用曲线救国，提前下载好所有的依赖安装包。那么怎么下载所有依赖呢，可以这么作。

1.用apt depends查看所有依赖包

>:apt depends xmlcopyeditor
xmlcopyeditor
  依赖: libaspell15 (>= 0.60.7~20110707)
  依赖: libc6 (>= 2.14)
  依赖: libexpat1 (>= 2.0.1)
  依赖: libgcc1 (>= 1:3.0)
  依赖: libpcre3
  依赖: libstdc++6 (>= 5.2)
  依赖: libwxbase3.0-0v5 (>= 3.0.4+dfsg)
  依赖: libwxgtk3.0-0v5 (>= 3.0.4+dfsg)
  依赖: libxerces-c3.2
  依赖: libxml2 (>= 2.7.4)
  依赖: libxslt1.1 (>= 1.1.25)
  建议: xmlcopyeditor-dbg (= 1.2.1.3-3)

2.用>:apt depends xmlcopyeditor | awk '{ if(NR==1){print $1} else{print $2} }' 过滤提取出包的名字

 
>:apt depends xmlcopyeditor | awk '{ if(NR==1){print $1} else{print $2} }'

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libstdc++6
libwxbase3.0-0v5
libwxgtk3.0-0v5

3.用apt download命令下载所有依赖包到当前目录下，注意是当前目录下。

>:apt depends xmlcopyeditor | awk '{ if(NR==1){print $1} else{print $2} }' | xargs apt download

补充：

apt -d install xxx.deb命令，安装时同时下载到 /var/cache/apt/archives/

apt clean 清空目录 /var/cache/apt/archives/

apt -d reinstall xxx.deb命令，重新安装，同时下载到 /var/cache/apt/archives/
