Certbot Renewal Configuration File - installer = webroot Doesn't Work

I am unable to run renew on my domains and sub domains. My uninformed guess is that certbot-auto has updated and the renewal configuration is no longer valid.

My domain is:


I ran this command:

certbot-auto renew --dry-run

It produced this output:

Processing /etc/letsencrypt/renewal/ganchrow.com.conf
Cert is due for renewal, auto-renewing...
Attempting to renew cert from /etc/letsencrypt/renewal/ganchrow.com.conf produced an unexpected error: An object does not implement interface <InterfaceClass certbot.interfaces.IInstaller>

        . Skipping.

My operating system is (include version):

Ubuntu 16.04.2 LTS 3.13.0-108-generic

My web server is (include version):

nginx/1.10.0 (Ubuntu)

Cerbot version:

certbot 0.14.1

I can login to a root shell on my machine (yes or no, or I don’t know):


Here is the file contents ganchrow.com.conf:

# renew_before_expiry = 30 days
cert = /etc/letsencrypt/live/ganchrow.com/cert.pem
privkey = /etc/letsencrypt/live/ganchrow.com/privkey.pem
chain = /etc/letsencrypt/live/ganchrow.com/chain.pem
fullchain = /etc/letsencrypt/live/ganchrow.com/fullchain.pem
version = 0.12.0
archive_dir = /etc/letsencrypt/archive/ganchrow.com

# Options used in the renewal process
authenticator = webroot
installer = webroot
account = 75b3d80dce4eed74f9faa78cd4c62133
rsa_key_size = 4096
webroot_path = /usr/share/nginx/html,
ganchrow.com = /usr/share/nginx/html
www.ganchrow.com = /usr/share/nginx/html

Thanks for your help.
