It seems there is an issue with package repository. What is your operating system ?

But you should read easyengine tutorials about email configuration, because elidaprado.com.br is not a fqdn

@virtubox Why do you say elidaprado.com.br is not a FQDN?

Because FQDN is a subdomain like your.domain.tld. It could not be just yourdomain.tld.
