Change notification email

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version): Ubuntu 16.04.1 LTS

The operating system my web server runs on is (include version): UNIX

My hosting provider, if applicable, is: AWS

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

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): letsencrypt 0.4.1

I want to change notification email. need help.

You have to use your ACME client to update the email addresses assigned to each of your ACME accounts.

(You probably have one account per server. Maybe also a second one for the Let’s Encrypt staging environment, but that’s less important.)

letsencrypt 0.4.1 doesn’t support that. You have to upgrade to a newer version.

(The project was also renamed from letsencrypt to Certbot, but the program is installed as both certbot and letsencrypt for backwards compatibility.)

You can use the Certbot PPA to upgrade by doing something like:

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
sudo apt update
sudo apt full-upgrade
sudo apt install certbot

Then you can change your email address with:

sudo certbot update_account -m
