Latex font not loadable error causing build failure for R package

Hi there, (new here, apologies if I’m not following etiquette).

I’m having difficulty making one of my R packages (RobinHankin/lorentz) pass the build process on travis; the package is clean on CRAN. There was a thread on inconsolata.sty not long ago that may or may not be related.

The error message I get is:

Running ‘texi2dvi’ on ‘lorentz.tex’ failed.
LaTeX errors:

But as you can see from the commits, I’ve tried with increasing frustration) lots of things with no success. Can anyone advise?
