linux - letsencrypt-auto 无法正确创建证书

Question

我正在遵循本指南:https://www.digitalocean.com/community/tutorials/how-to-set-up-let-s-encrypt-certificates-for-multiple-apache-virtual-hosts-on-ubuntu-14-04 .

我确实按照教程中所示提取了 git 存储库，当我运行命令 ./letsencrypt-auto --apache -d example.com -d www.example.com 时，其中example.com 是我的实际站点，它确实要求我提供联系人的电子邮件地址，但它没有弹出剩余的操作，而是弹出了以下错误消息:

发生意外错误:
NameError:在封闭范围内赋值之前引用了自由变量“addrs”


但它创建了证书。我尝试了网站 ssllabs，但它说服务器正在监听端口 443，但没有提供安全传输，https://example.com 也没有提供。实际工作(未加载)。

我尝试多次再次运行它，甚至重新拉取 git 存储库，但总是出现相同的错误消息。

这是什么问题，我该如何解决？

这里有一个关于此错误的已关闭问题，并且已进行修复:

我必须手动应用补丁。希望 0.4.1 发布时这不会成为问题。
