Well, I think the source or network has not been configured properly, but now I really don’t know how to modify it. Which great god can help solve it or give some ideas?
I am also a docker learner. I hope you can help me a lot. I am very grateful.

Did you restart after configuring 163 images? I feel that I have to go to the official mirror to get it.
