I'm trying to install glance service from https://docs.openstack.org/glance/rocky/install/install-ubuntu.html (here). the problem is in verify operation, when I enter the command openstack image create "cirros" \ --file cirros-0.4.0-x86_64-disk.img \ --disk-format qcow2 --container-format bare \ --public I get error

HTTPInternalServerError (HTTP 500)

with --debug flag here is the error part:

http://controller:9292 "GET /v2/schemas/image HTTP/1.1" 500 0
Request returned failure status 500.
