上传镜像提示HTTPInternalServerError (HTTP 500)

openStack新手一枚，今天在搭建过程中遇到下面这个问题，google良久无法找出问题原因：
系统：Ubuntu 16.04
openStack版本：Queen
搭建操作步骤参考的是官网手册：https://docs.openstack.org/glanc ... install-ubuntu.html
在上传镜像时提示HTTPInternalServerError (HTTP 500)
root@controller:~# openstack image create "cirros"   --file cirros-0.3.5-x86_64-disk.img   --disk-format qcow2 --container-format bare   --public
