I am using Jupyter for the first time. I am trying to download a notebook "as PDF via LaTeX". However, messages pop up indicating that the required files
tex\xelatex\xetex-def\xetex.def (part of the xetex-def package)
tex\xelatex\xetexurl\url.sty (part of the xetexurl package)
are missing. The problem is that neither package seems to be available at
Using the MiKTeX Package Manager (which I have synchronized), I have installed the graphics-def package, which apparently includes the xetex.def file. But the downloading process is still not working.
Any help would be greatly appreciated.
