Latex PDF building?

Hey!

Sorry to bump this thread, I’ve just used the textlive image and it worked great!
My question is: how can I install some prerequisites (I have custom fonts I need to install before building)? I tried using

dependencies:
  pre:
    - wget https://github.com/MihailJP/Inconsolata-LGC/releases/download/LGC-1.3.0/InconsolataLGC-1.3.0.tar.xz
  ...

But that didn’t seem to work when using the texlive docker image (I didn’t see any output from those commands, and my build failed for not finding the fonts). I ended up calling each command from steps.run

Is there a better way? Am I holding this wrong? (sorry, very new to CircleCI and/or docker)
