bin/rdfunit -d /...../Dataset.rdf -o ttl

I get this error:

Hi Andrea,

The service lov.okfn.org is offline, that' s what the error is about.
We need to wait untill it is online again.

Best,
Roland

Hi Roland, thanks.
Can I know what type of service is? What does it provide?

LOV is Linked Open Vocabularies which is a service maintained by OKFN that provides an api for resolving vocabularies. Sadly enough it is hacked days ago and it is unclear when it will come up again.
