Letsencrypt Hassbian issue

I’m rebuilding my hassbian install and I’m going through what appear to be some new directions for letsencrpyt. I can’t get past the steps below it keeps asking me for the sudo password for the user homeassistant.

If you’re running the ‘standard’ setup on a Raspberry Pi the chances are you just logged in as the ‘pi’ user. If not, you may have logged in as the Home Assistant user. There are commands below that require the Home Assistant user to be on the sudoers list. If you are not using the ‘standard’ pi setup it is presumed you will know how to get your Home Assistant user on the sudoers list before continuing. If you are running the ‘standard’ pi setup, from your ‘pi’ user issue the following command (where hass is the Home Assistant user): $ sudo adduser hass sudo

If you did not already log in as the user that currently runs Home Assistant, change to that user (usually hass or homeassistant - you may have used a command similar to this in the past):

$ sudo su -s /bin/bash hass
Make sure you are in the home directory for the HA user:

$ cd
We will now make a directory for the certbot software, download it and give it the correct permissions:

$ mkdir certbot
$ cd certbot/
$ wget https://dl.eff.org/certbot-auto
$ chmod a+x certbot-auto
Now we will run the certbot program to get our ssl certificate. You will need to include your email address and your DuckDNS URL in the appropriate places:

$ ./certbot-auto certonly --standalone --preferred-challenges http-01 --email [email protected] -d examplehome.duckdns.org

I ran

sudo adduser homeassistant sudo

and received

Adding user homeassistant' to group sudo’ …
Adding user homeassistant to group sudo
Done.

But i still get prompted for a password. I don’t recall installing letsencrypt to the venv last time.
