如何更新Certbot版本？

Question

我正在运行,certbot --apache但我收到以下错误:

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0.10.2在Debian 8.10上

我想升级到0.21.0,这应该解决问题https://community.letsencrypt.org/t/certbot-0-21-0-release/50725

但我尝试了apt-get update/upgrade,我得到以下内容:

certbot is already the newest version.
certbot set to manually installed.

有关如何更新的任何建议？

Answer 1

不知道我是怎么错过这个的.从安装文档https://certbot.eff.org/docs/install.html#certbot-auto

user@webserver:~$ wget https://dl.eff.org/certbot-auto
user@webserver:~$ chmod a+x ./certbot-auto
user@webserver:~$ ./certbot-auto --help

Answer 2

您可以检查您的软件版本，但这有效：

sudo apt-get update -y
sudo apt-get install software-properties-common
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update -y
sudo apt-get install certbot python-certbot-apache
certbot --version

Answer 3

sudo apt update
sudo apt install --only-upgrade certbot

使用 nginx 在 ubuntu 上尝试过，对我来说没有问题。
