LetsEncrypt Certbot renewal requiring an account choice

[x5en7]

Today I was alerted that the certificate for MIAB had expired, and did not automatically renew. When trying to manually provision a new cert, the message below is the response:

Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator webroot, 
Installer None Missing command line flag or config entry for this setting: Please choose an account 
Choices: ['mailserver@2019-09-02T01:50:35Z (8e3c)', 'mailserver@2018-11-23T15:59:13Z (9a3e)']

My questions are:

1. I do not see any accounts in /etc/letsencrypt/accounts, so I’m not sure where these accounts listed are coming from. If I try certbot unregister, it replies with 0 accounts found. Where can I manage these invisible accounts, and remove 1 of them?

2. How do I pass an account id to the management/ssl_certificates.py script that is trying to provision the certificate?

Cheers!

Try the solution suggested here and see if that helps:

Multiple Let's Encrypt accounts preventing certificate from renewing

The ACME client creates and handles everything about your “account” that is required when talking to the Let’s Encrypt servers that issue the certificate. Normally with MIAB upgrades this isn’t an issue, because you’re running off the same original install (and LE “account”), just upgrading. With the jump from .30 to .40, you have to do a new install onto 18.04. During the install, LE creates a new account to handle the certificates, but your old account is also restored when you go through the…

In the same situation I had two folders in /user-data/ssl/lets_encrypt/accounts or /user-data/ssl/lets_encrypt/accounts/acme-v02~ypt.org/directory/ (don’t remember for sure)
Deleted one of the accounts and rerun management/ssl_certificates.py and everything worked ok.
