Failed to renew сertificates

My domain is: politkrytyka.org

I ran this command: sudo certbot renew --dry-run

It produced this output:

It looks like Fedora 27 is EOL. It’s missing required updates to the python3-acme package to be compatible with the Let’s Encrypt’s ACME/RFC8555 implementation.

I think unless you get Certbot from snaps or from certbot-auto, you won’t be able to use it any longer.

I’ve filed https://github.com/certbot/website/pull/607 to update the minimum version on the Certbot website to Fedora 31.
