Magento2 Composer ‘Module-Wishlist’ Error – How to Fix

I'm trying to update my magento version to 2.2 (from 2.1.7) but had a "Content Dependency" error, but have narrowed down the issue a module, the "module-wishlist-sample-data" magento module.

When I try to update composer I get the following error:

Your requirements could not be resolved to an installable set of packages.
