While PDF docs work fine on RPM-based distros, it causes conflicts on Debian & friends. There are multiple root causes here: - the latex_elements still resambles the one from Sphinx 1.x times, where font configurations were stored under "preamble". It doesn't follow the current recommended way from Sphinx documentation: https://www.sphinx-doc.org/en/master/latex.html - instead of setting the main font, from where other fonts are derivated, it sets romanfont; - "fontenc" is not set. This allows the *.tex output file to contain an UTF-8 incompatible fontset: \usepackage[T1]{fontenc} Address such issues to help preventing incompatible usage of both T1 font and UTF-8 ones that comes from DejaVu font family. On some distros, this even generate a LaTeX font warning about corrupted NFSS tables like this (I got it when running it in interactive mode): Package: fontenc 2021/04/29 v2.0v Standard LaTeX package LaTeX Font Info: Trying to load font information for T1+lmr on input line 11 6.
