Anki 上的 LATEX 无法正常显示； Ubuntu 18.10

Question

Folks - I'm trying to display the basic command as below (one of many examples):

Does the sum below converge? [latex]\\begin{displaymath}\\sum_{k = 1}^{\\infty}\\frac{1}{k}\\end{displaymath}[/latex]

However it produces the following error:

Does the sum below converge? Error executing dvipng. Generated file: /tmp/anki_temp/tmp.tex

This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2019/dev/Debian) (preloaded format=latex) restricted \\write18 enabled. entering extended mode (./tmp.tex LaTeX2e <2018-04-01> patch level 5 (/usr/share/texlive/texmf-dist/tex/latex/base/article.cls Document Class: article 2014/09/29 v1.4h Standard LaTeX document class (/usr/share/texlive/texmf-dist/tex/latex/base/size12.clo)) (/usr/share/texlive/texmf-dist/tex/latex/base/inputenc.sty) (/usr/share/texlive/texmf-dist/tex/latex/amsfonts/amssymb.sty (/usr/share/texlive/texmf-dist/tex/latex/amsfonts/amsfonts.sty)) (/usr/share/texlive/texmf-dist/tex/latex/amsmath/amsmath.sty For additional information on amsmath, use the `?' option.

I've got Ubuntu 18.10 running with Anki (Version 2.1.5 Qt 5.9.2 PyQt 5.9) and "sudo apt install texlive-latex-extra" installed.

Any help would be highly appreciated.

Well, dvipng was missing.

Run sudo apt-get install dvipng
