o Tweaked exception message to be more presice with respect to remote repos - First, don't eliminate repos with duplicate ids. Duplicate repos should have been merged up-front, if they weren't this is a bug and should be apparent in the diagnostic output - Second, be explicit about the case where no repos are defined to distinguish that from the case where the exception creator did not know the repos (==null)
