无法拉动Docker hello-world

我阅读并尝试了有关此问题的所有post，Docker Docs中的每一行。 不幸的是我的问题仍然存在。

这是发生了什么事情：

bayram@bayram-ubuntu-desktop:~$ sudo docker pull hello-world Using default tag: latest Error response from daemon: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: Get https://auth.docker.io/token?account=bayram&scope=repository%3Alibrary%2Fhello-world%3Apull&service=registry.docker.io: EOF bayram@bayram-ubuntu-desktop:~$ 

奇怪的是，30秒后我跑了同样的命令，得到了不同的回应：

 bayram@bayram-ubuntu-desktop:~$ sudo docker pull hello-world Using default tag: latest Error response from daemon: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: EOF bayram@bayram-ubuntu-desktop:~$ 

3秒后再次尝试：

 bayram@bayram-ubuntu-desktop:~$ sudo docker pull hello-world Using default tag: latest latest: Pulling from library/hello-world 78445dd45222: Pulling fs layer error pulling image configuration: Get https://registry-1.docker.io/v2/library/hello-world/blobs/sha256:48b5124b2768d2b917edcb640435044a97967015485e812545546cbed5cf0233: EOF bayram@bayram-ubuntu-desktop:~$ 

有没有人知道什么是错的？

我坐在代理之后，使用Ubuntu 16.04桌面。 我补充说

 [Service] Environment="HTTP_PROXY=user:pwd@123.456.789.123:1080/" 

到/etc/systemd/system/docker.service.d/http-proxy.conf ，然后运行systemctl daemon-reload并重新启动Docker守护进程。

这是我的docker信息：
