@casperdcl looks like some issue with font breaking the CI on build step. I tried making this change which resulted into this workflow run eventhough it passes, but now logs throw warnings like this. Can we ignore these warnings? and is the approach looks correct?

I've reverted the change for now.

I just un-reverted the change :)

unfortunately b8b2637 only installs the font in the md -> latex step (which is great) but doesn't touch the latex -> pdf step (which uses the docker image from https://github.com/xu-cheng/latex-action)...

Looks like you could use xu-cheng/latex-action.with.extra_fonts?
