Note that this Ubuntu bug is likely inherited from Debian Bug #892181
(ruby-ncurses fails to load with Ruby 2.5):
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892181
The Debian bug was filed on 2018-03-06, at approximately the time that
the Ubuntu 18.04 cut of Debian packages would have been taken. However,
the upstream Debian bug is now fixed, as of 2018-06-13.
