Error occurred in deployment step ‘Retract Solution’: Attempted to perform an unauthorized operation

You can fix it by setting the access policy for the current user deploying the SharePoint Solution.

Go to Central Administration - Manage web applications (under Application Management).

Please select the SharePoint application and then press "User Policy" in the ribbon. Over there you add your user you want  deploy with and give him full control.
