Describe the bug

I was trying to add an SSL certificate through Let's Encrypt DNS challenge and choosing Cloudflare as the DNS Provider. However, an error occurred, which seems implying there is conflicting dependencies between certbot-dns-cloudflare and cloudflare.

CommandError: ERROR: Cannot install certbot-dns-cloudflare==4.1.1 and cloudflare==4.0.* because these package versions have conflicting dependencies. ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts
