Je ne réussis plus à compiler avec LuaLaTeX. Alors que ma TeX Live est à jour, j'obtiens ceci : (LaTeX) The L3 programming layer in the LaTeX format (LaTeX) is dated 2025-07-19, but in your TeX tree the files require (LaTeX) at least 2025-07-20. For immediate help type H <return>. ... l.78 \ExplLoaderFileDate{expl3.sty}} L'aide me renvoie ceci : The cause seems to be an old format file in the user tree. LaTeX found these files: - /home/user/.texlive2025/texmf-var/web2c/luahbtex/lualatex.fmt - /usr/local/texlive/2025/texmf-var/web2c/luahbtex/lualatex.fmt Try deleting the file in the user tree then run LaTeX again. LaTeX will abort loading the incompatible support files but this may lead to later errors. Please ensure that your LaTeX format is correctly regenerated. Je suis assez étonné que l'on me propose d'effacer manuellement des fichiers. C'est bien le TeX Live Manager `tlmgr` qui s'occupe de ça, non ? ? Dans l'attente, je ne fais rien, plutôt que de tout casser.
