ubuntu12.04 - docker pull ubuntu 总是出错

Question

从docker的索引中下载ubuntu时总是报如下错：

Error while retrieving image for tag: (strconv.ParseInt: parsing "": invalid syntax); checking next endpoint

运行的命令：
docker pull ubuntu
或者
docker pull learn/tutorial
报的错误是一样的

大家有遇到过类似的情况吗？是怎么解决的

Answer 1

Found a way:
Missed two places:
1. Add Docker’s repository to your local keystore

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9

2. Install according to the official simple installation script. I don’t know why the docker pull ubuntu installation always fails

curl -s https://get.docker.io/ubuntu/ | sh

3. If you want to change the version, change it through docker pull ubuntu:12.04
