Help geting cerbot to work again

I’m trying to re setup my certs again from reinstalling ubuntu server. I’m using this to get https for qbittorrent. I’m following this guide here:

My domain is:

I ran this command:
(as root) certbot --nginx --redirect --agree-tos --hsts --staple-ocsp --email My Email -d

It produced this output:

Plugins selected: Authenticator nginx, Installer nginx
Obtaining a new certificate
Performing the following challenges:
An unexpected error occurred:
AttributeError: module ‘acme.challenges’ has no attribute ‘TLSSNI01’
Please see the logfiles in /var/log/letsencrypt for more details.

The operating system my web server runs on is (include version):
Ubuntu Server 20.04 lts

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): certbot 0.40.0

There are some known issues with certbot on this new O/S version.
[see: Certbot install fails on Ubuntu 20.04]
I don’t know when it will get fixed.
In the interim, you might be able to use certbot-auto or acme-sh
