LyX ⇒ PDF export fails with pdflatex and LuaTeX

[TheMart]

Dear all,

I am using LyX 2.3.3 on Ubuntu 18.04 (and i have been doing so (successfully) for almost two years). However, I recently switched laptops and therefore needed to reinstall ubuntu.

On the new machine, LyX fails to export pdf files via pdflatex and LuaTeX. There is no pdf file after running export. The only thing that does work is using ps2pdf.

Here's the message output from Lyx:

Any idea what might be wrong?

Oh yeah... running pdflatex (manually) on LaTeX code produced by LyX does work.
