尝试使用yum在aws linux上安装confluent platform（kafka）3.1.1 . 获取PYCURL错误22 - “请求的URL返回错误：404 Not Found”

我按照this wiki doc中链接的说明在我运行amazon linux（版本2016.09）的EC2实例上安装汇合平台 . 我做了一切，包括：

$ sudo rpm --import http://packages.confluent.io/rpm/3.1/archive.key

使用以下内容创建了/etc/yum.repos.d/confluent.repo：

[Confluent.dist]
name=Confluent repository (dist)
baseurl=http://packages.confluent.io/rpm/3.1/6
gpgcheck=1
gpgkey=http://packages.confluent.io/rpm/3.1/archive.key
enabled=1

[Confluent]
name=Confluent repository
baseurl=http://packages.confluent.io/rpm/3.1
gpgcheck=1
gpgkey=http://packages.confluent.io/rpm/3.1/archive.key
enabled=1

然后呢

$ sudo yum clean all
$ sudo yum install confluent-platform-2.11

但是我收到了以下错误：

它看起来像rpm文件只是不是我的互联网连接或任何问题，因为当我更改我的confluent.repo文件指向http://packages.confluent.io/rpm/3.0时，除了librdkafka之外，kafka包下载就好了 . 任何建议将不胜感激，不知道还有什么可以尝试 .
