This is after my series, with doesn't deal with imagemagick/inkscape,
it only fixes broken texlive dependencies and fix font handling:

Yes. After having texlive dependencies fixed, and addressing the broken
conf.py file that is not aligned with modern Sphinx practices, it passed
on all three scenarios.

Please notice that addressing image was not the intent of this series.

The goal was *just* to fix texlive dependencies and fix text font
mapping that were causing troubles on Ubuntu and on other distros.


Thanks,
