What is the latest Unity version for Ubuntu linux

Hi. I am trying to find the latest Unity build for Ubuntu linux e.g. deb package.
Is there a 2018 Unity for Linux build?
I cannot find a .deb for 2018 but I can find 2017.2.0f1 deb package for Ubuntu. Is 2017.2.0f1 the latest Ubuntu .deb package?

My thinking is if I have 2018 or 2017 installed both under Ubuntu and Win 10 that I could easily modify projects between the two operating systems.
Thanks for any advice.
