I can no longer renew my domain

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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:forgetmenotflowerboutique.com

I ran this command:certbot renew

It produced this output:An unexpected error occurred:
ImportError: cannot import name le_util
Please see the logfile '/tmp/tmpR9W1aM' for more details.
My web server is (include version):

The operating system my web server runs on is (include version):Ubuntu 16.04.3 LTS (xenial)

My hosting provider, if applicable, is: DigitalOcean

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): Yes

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot --version gives me the same error as above. An unexpected error occurred:
ImportError: cannot import name le_util
Please see the logfile '/tmp/tmpvbs92e' for more details.

Have you always used Certbot to get your certs?

In the past you got a fresh cert every 30 days (Certbot default is every 60 days).

What has changed?

[MikeMcQ]

I see you got a new cert but you probably need to get a different one. The latest only has your root domain name and not the www subdomain. Requests to your www domain will fail with a cert error (see here).

Also, I also see you are now getting a cert with R3 intermediate rather than E1. The E1 is issued for ACME accounts in the allow-list for ECDSA intermediates.

Did you lose track of your ACME account info?

The module le_util was renamed back in 2016, which makes me believe your Certbot version is very old. There's probably a mismatch between some versions.

Please update everything related to Certbot to the most recent version, preferably using snap.
