TexLive 2019 lualatex doesn't compile document

Question

I have a document that compiles fine under pdflatex. But when I use lualatex the compilation process ends without doing anything.

The log file has just these line:

This is LuaTeX, Version 1.10.0 (TeX Live 2019)  (format=lualatex 2019.6.18)  18 JUN 2019 09:03

Lua module: luaotfload-log 2019-05-18 2.97 luaotfload submodule / logging

This error appears even with this minimal document:

\documentclass{article}

\begin{document}
Hello world!
\end{document}

I am running TeXLive 2019 running in ubuntu 19.04. TexLive 2018 work ok.

The output in the terminal doesn't show any error:

This is LuaTeX, Version 1.10.0 (TeX Live 2019) 
 restricted system commands enabled.
(./test.tex
LaTeX2e <2018-12-01>

Rebuilding the format didn't work.

But the plain TeX document

Hello
\bye

works fine.

Any idea where to start looking for clues?

EDIT This is my TeXLive 2019 installation profile.

The problem was that TEXMFVAR was defined as the same as TEXMFSYSVAR in texlive.profile. Those two folders are owed by root, so luatex is not able to create necessary files while compiling.

The solution is to define TEXMFVAR to other folder; for example, $USR/.texlive/2019
