I googled around, most posts said to update mono from a very old buggy version and one mentioned the Unity addon "VSCode" which hasn't helped.

Yes, you'll likely need to update your version of Mono. For Ubuntu, I recommend using the latest stable build here: http://www.mono-project.com/download/stable/#download-lin

Updating has fixed the issue. I just want to add incase anybody gets this same issue, the 16.04 mono repo will work with 17.10, which I assumed it wouldnt which is why I didnt try updating sooner.

Mono can be amazingly resilient on Linux. :smile:
