Research direction

Start by reproducing the rstan installation command on Ubuntu 20.04.1 with R 4.0.3 and inspect the project's installation guidance for the ppa:marutter/c2d4u3.5 reference. Done means the documented installation path no longer produces the reported 404, or the supported alternative is clearly documented.
