Hi, I’d really appreciate any help with the following:

Am using CentOS Linux 7
Domain: clefrance.co.uk
nginx version: nginx/1.12.2
I have sudo shell access

All attempts to run certbot give:An unexpected error occurred:
ImportError: cannot import name constants

Thanks!

This kind of error usually happens as a result of trying to install Certbot from multiple different sources, and ending up with a mix of package versions.

Where you did install Certbot from?

Thanks for the reply az.

I do not know because my usual server guy has disappeared. But if it helps, running ‘whereis certbot’ gives me a single loction: /usr/bin/certbot
