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?

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
