linux 下载deb和其依赖

1. 安装apt-rdepends

   apt install apt-rdepends

2. 下载依赖，比如vim

   apt download $(apt-rdepends vim | grep -v "^ ")

3. 如果出现错误比如：E: Can't select candidate version from package debconf-2.0 as it has no candidate可以使用一下命令：

   apt-get download $(apt-rdepends vim | grep -v "^ " | sed 's/debconf-2.0/debconf/g')

4. 拷贝deb文件到新的环境，安装之：dpkg -i *
