The default version of certbot that is available in the repository will result in the following error message if you try to run `certbot --apache`:

{{{
Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.
}}}

As discussed in the [[https://community.letsencrypt.org/t/solution-client-with-the-currently-selected-authenticator-does-not-support-any-combination-of-challenges-that-will-satisfy-the-ca/49983|LetsEncrypt Forums]] this is due to a security issue that existed in the old client.
