"missing signature key" when pull latest image (21.0.2) from quay.io for Centos 7

1

I’m try to get the latest image (21.0.2) by tag and digest from quay.io in Centos 7 but it can be done with an error:

[root@centos7-server:~]# docker pull quay.io/keycloak/keycloak:21.0.2
Trying to pull repository quay.io/keycloak/keycloak ...
missing signature key
[root@centos7-server:~]# docker pull quay.io/keycloak/keycloak@sha256:c2f9406152649d32671d43a6c04077fe9aac31a2c36ebfdc83aa55337e90ef00
Trying to pull repository quay.io/keycloak/keycloak ...
missing signature key

This error will not appear if I pull the older version like 20.0.3
FYI, I’m using docker version 1.13.1 when pull the image
