biber cannot find global bibliography

Using MikTeX for Linux, Ubuntu, and LuaLaTeX.
bib file "Références.bib" is located in ~/texmf/bibtex/bib/Références/ with ~/texmf added as a root in MikTeX Console.
tex file ("a" is not a valid reference, but I’d recognize the error):

documentclass{article}

usepackage{biblatex}
addbibresource{Références.bib}

begin{document}
 cite{a}
end{document}

biblatex output:

*****
*****     Biber output: 
*****     cd "/home/ubuntu/yann/Documents/Scolaire/1A/Stage/Rapport stage/Présentation rapport"
*****     biber test
*****

biber works when the bibliography is put in the same directory.
What would be the correct thing to put in addbibresource?
