Hi Peter, I've seen the same error on a fresh 18.04 system I have installed last week, and the solution was to add the Open Sans fonts to the user folder (~/.fonts) and rebuild X font cache.
By the way, Ubuntu 17.10 was Wayland, Ubuntu 18.04 is not Wayland, as far as I know. And I had Pharo working on both.
