第一步：通过dig @114.114.114.114 registry-1.docker.io找到可用IP
navy@deepin:~/Desktop$ dig @114.114.114.114 registry-.docker.io ; <<>> DiG 9.11.--Debian <<>> @114.114.114.114 registry-.docker.io

第二步：尝试修改/etc/hosts强制docker.io相关的域名解析到其它可用IP
vim /etc/hosts
添加一个可用IP：
34.200.28.105 registry-.docker.io
保存之后重试:
navy@deepin:~/Desktop$ sudo docker pull ubuntu
