使用 certbot 更新证书时版本无效

使用 certbot 更新证书时版本无效

我有一台安装了 certbot 的 Let's encrypt 证书的服务器。我想使用以下命令来更新它 sudo certbot renew --force-renewal

但我收到一个错误:

Saving debug log to /var/log/letsencrypt/letsencrypt.log

我有 Ubuntu 20.04.4 LTS、Python 3.8.10,我该怎么办?

答案1

我在 Ubuntu 18.04 中遇到了同样的问题,这是由 pyOpenSSL 23.2.0 版本引起的。降级到 23.1.1 后,它又恢复正常了:

pip3 install pyOpenSSL==23.1.1

答案2

今天我在未升级的 Debian 10 机器上遇到了这个问题。前段时间它还能正常工作,但现在我遇到了同样的错误(无效版本。X509Req 的唯一有效版本是 0.. 跳过。)。我通过简单升级 certbot 解决了这个问题:

pip3 install -U certbot

这很有帮助,certbot renew效果很好。现在,pip freeze显示为我安装的这些相关软件包:

certbot==2.7.4
pyOpenSSL==24.0.0

我认为使用最新版本的安全库比降级到旧版本要好得多。
