    Works fine for (if I add a font). Are you sure that your system is up-to-date? Imho \__fontspec_pass_args:nnn has been removed from a current fontspec, see tex.stackexchange.com/questions/350664/… Apr 13, 2017 at 8:57
  • Dear @Ulrike.. thanks for your response. What's your point about "up-to-date" ? i just installed full tex-live and don't know what else should be done.

  • Run the texlive manager: tlmgr update --list and check if there updates. Apr 13, 2017 at 9:46
  • copied from terminal : Cannot determine type of tlpdb from /root/texmf! cannot setup TLPDB in /root/texmf at /usr/bin/tlmgr line 5713.

  • Did you install a standalone texlive or something from your linux distribuation? Apr 13, 2017 at 9:51

The problem is bad installation of TexLive (using debian packages). The Correct way is to install from ctan.org. I just downloaded an iso image from ctan mirrors and every thing just works ! Thank you @gernot & @Ulrike Fischer for your helpful comments.
