我已经坚持了一段时间。我一直在尝试通过certbot免费获得我的网站的SSL证书。按照网站上my configurations的说明，我尝试了以下说明：
sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
到目前为止一切顺利！至于下一条指令，一切也都成功运行了：
sudo apt-get install certbot python-certbot-apache
对于列在here的第4步，我选择了自动选项，却被此消息抛出：
Saving debug log to /var/log/letsencrypt/letsencrypt.log

我输入的域名是：

然后我的真正的问题开始了，因为它向我抛出了以下错误：（您可以跳过此错误消息，因为它很长，请向下滚动以查看摘要）

Summary：我需要将域添加到“ somewhere”（我不知道在哪里！）
在这里发布问题之前，我已经阅读了许多文档（here，here和here）。
配置：
实例类型：通过Lightsail启动的Amazon EC2 Linux，Ubuntu 16.04 xenial服务器（Django服务器，Bitnami）
服务器：Apache
（（实例的端口80已打开）
我的域也已在AWS Route53中注册（仅在需要时提及）。
问题：如何克服此错误并为我的网站安装SSL？
运行此：
apt -y install certbot
sudo服务apache2停止
certbot certonly --standalone -d domain.xx -d www.domain.xx
即是。
