"Something wicked happened" Installing plugins

Hey, i'm new to OMV and linux, everytime i try to install a plugin or perform a update i get an error similar to this in the attachment. The majority of the errors are "No address associated with hostname". Does anyone know what i'm doing wrong or have configured incorrectly.

Spend hours searching for the answer, create a post and find the answer 30 seconds later. Naturally.
I had not had a DNS server setup.
