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。

我确实拉了git repo，如教程中所示，当我运行命令./letsencrypt-auto --apache -d example.com -d www.example.com，其中example.com是我的实际网站时，它确实问我联系人的电子邮件地址，但后来弹出剩余的动作，它提出了这个错误信息：

An unexpected error occurred: NameError: free variable 'addrs' referenced before assignment in enclosing scope

但它创建了证书。我试过网站ssllabs，但它说服务器正在侦听端口443，但没有提供安全传输，https://example.com实际上也没有工作（没有加载）。

我尝试多次再次运行它，甚至重新拉动git repo，但总是出现相同的错误信息。

这是什么问题，我该怎么办呢？

此错误存在已解决的问题，并已进行修复：

我必须手动应用补丁。希望当0.4.1出现时，这不会成为一个问题。

letsencrypt-auto无法正确创建证书
