证书未到期更新，但模拟更新 dry 运行

Question

我正在使用 certbot-auto 为我的域名生成证书 https。我使用这样的命令

sudo ./certbot-auto

没关系，但是当我更新证书时使用命令

sudo ./certbot-auto renew --dry-run

无法续订证书并显示如下错误消息：

/root/.local/share/letsencrypt/lib/python2.6/site-packages/cryptography/__init__.py:26: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of cryptography will drop support for Python 2.6

请帮帮我

您运行在您的问题sudo ./certbot-auto renew --dry-run中使用的命令用于测试更新。如您的日志所示，一切顺利，测试成功。

当您希望续订证书时，运行 sudo ./certbot-auto renew --quiet 将起作用。当证书在 30 天内过期或已经过期时，您可以续订证书。

可以在 Certbot documentation and Certbot userguide 中找到更多详细信息。
