我正在运行 certbot --apache
,但是出现了以下错误:
Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org
Obtaining a new certificate
Performing the following challenges:
Client with the currently selected authenticator does not support any
combination of challenges that will satisfy the CA.
安装的版本为Debian 8.10上的
0.10.2
。我想升级到0.21.0,这应该可以解决问题。详情请见https://community.letsencrypt.org/t/certbot-0-21-0-release/50725。
但是我尝试使用apt-get update/upgrade命令进行升级时出现以下错误:
certbot is already the newest version.
certbot set to manually installed.
有关如何更新的任何建议吗?
