The error prompts are:

Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/owncloud/images. You may want to check your internet connection or if you are behind a proxy. I have tried vpn and ss, but it is useless. Who can teach me how to do it?
The speed with which the official Docker Hub is mirrored by DaoCloud is really good. The command is simple
dao pull nginx:latest.
Also, it is not useful to pull the mirror image on Docker Hub.
docker pull nginx:latestIs this an order? Why wget?
