lyx 2.3.6-1 (ppc64el binary) in ubuntu hirsute

 LyX is an almost WYSIWYG-frontend for LaTeX. It makes the power and
 typesetting quality of LaTeX available for people who are used to
 word processors. Since LyX supports LaTeX's concept of general
 mark-ups, it is even easier and faster to create professional quality
 documents with it than with usual word processors. It is also
 possible to use LaTeX commands within LyX, so nothing of LaTeX's
 power is lost.
 .
 You can extend the functionality of LyX by installing these packages:
  * chktex: check for typographical errors
  * gnuhtml2latex: import HTML documents
  * groff: improved table formatting in plain text exports
  * librsvg2-bin, inkscape: use the SVG image format in LyX documents
  * linuxdoc-tools: export SGML LinuxDoc documents
  * mythes-*: use the OpenOffice.org/LibreOffice Thesaurus
  * noweb: import noweb files
  * rcs: integrated version control
  * sgmltools-lite: export SGML DocBook documents
  * texlive-xetex: use the XeTeX typesetting system
