> Any Idea how to fix the above letsencrypt error for 20.04 (as long as I didn’t have done the upgrade to 22.04)?

There is an explanation in the error message you shared on what should be done to fix the error. The error has nothing to do with `certbot`, and most probably with Virtualmin itself.

It seems that you don’t have DNS configured correctly for the domain. Please have a closer look at our Let’s Encrypt troubleshoot. I hope it helps:

Ok, I’ve got it to upgrade my first server from 20.04 to 22.04 and it seems that anything work as expected.  
Thanks for helping hands.

Only one question remains… it seems that IPv6 is never set as default to my new domains. Where can I set this up?

Ok, upgrade work as expected, now i have certbot-version 1.21.0 and requesting a certificate seems to work as expected.

👍🏼
