关于vagrant 在本地添加vagrant box时报错

The box failed to unpackage properly. Please verify that the box
file you're trying to add is not corrupted and try again. The
output from attempting to unpackage (if any):

x ./Vagrantfile
x ./vagrant_private_key
x ./box-disk001.vmdk: truncated gzip input
bsdtar: Error exit delayed from previous errors.

VirtualBox Vagrant 与制作 vagrant box 的版本一致（分别是 VirtualBox 5.1.8 和Vagrant 1.8.6）。系统一致都是Ubuntu 14.04 。

求大神解答
