问题
I am running certbot --apache but I get the following error:
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.
Version installed is 0.10.2 on Debian 8.10
I would like to upgrade to 0.21.0 which should fix the issue https://community.letsencrypt.org/t/certbot-0-21-0-release/50725
but I tried apt-get update/upgrade and I get the following:
certbot is already the newest version.
certbot set to manually installed.
Any suggestions on how to update?
回答1:
Not sure how I missed this. From the install docs 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

A bit of background from Let's Encrypt
Unfortunately, Let's Encrypt has stopped offering the mechanism that Certbot's Apache and Nginx plugins use to prove you control a domain due to a security issue
To get around this on an existing L.E installation before the updates, follow this solution if you're on Debian/Ubuntu:
certbot --authenticator standalone --installer apache -d <yourdomain(s)> --pre-hook "apache2ctl stop" --post-hook "apache2ctl start

On debian Stretch, just use:
apt-get install python-certbot-apache -t stretch-backports

On MacOS, use the following command to install certbot:
brew install certbot
Or if you have already installed certbot, use the following command to upgrade
brew upgrade certbot
