My domain is:
dev.wintouch.net
I ran this command:
certbot-auto certonly --manual --preferred-challenges DNS -d ‘dev.wintouch.net,*.dev.wintouch.net’
It produced this output:
Upgrading certbot-auto 1.0.0 to 1.1.0…
Replacing certbot-auto…
Creating virtual environment…

Installation succeeded.

I can sign on, and “sudo bash” to root.
I had just successfully installed certbot yesterday, and it was working, until it auto-updated when I ran it today.
When I repeated the command, it gave this output:
Error: couldn’t get currently installed version for /opt/eff.org/certbot/venv/bin/letsencrypt:

I tried the solution offered at
It gave no complaints until the final command,
/opt/eff.org/certbot/venv/local/bin/pip install cryptography interface
at which point, it complained:
