Installing JModelica to paperspace (cloud) machine with 4 cores running Ubuntu 16.04 (64-bit). I installed all of the required packages on a fresh install, but did not enforce the tested version numbers. This was done May 29, 2019. This isn't meant to be complete, but complementary to the installation instructions in the JModelica 2.2 manual.
