libertine font inaccessible

My main box out of commission and so I trying to run TeXLive on a 
backup machine. But a Tex document won't compile because it 
cannot find the libertine font. I dont' know if I orignally 
installed TeXLive on the machine as user or root and that may be 
the problem.

I have linux-libertine package installed on devuan excalibur.  
Font-manager confirms it is installed. The libertine oft files
are located in /usr/share/fonts/opentype/linux-libertine/
$ fc-list | grep libertine returns all the libertine styles, 

I register the font: ''
  $ fc-cache -fv | grep libertine
  /usr/share/fonts/opentype/linux-libertine
  /usr/share/fonts/opentype/linux-libertine:
	caching, new cache contents: 13 fonts, 0 dirs
  /usr/share/fonts/opentype/linux-libertine: skipping,
        looped directory detected

I made accessible to TeXlive
  # texhash
  texhash: updating /usr/local/share/texmf/ls-R...
  texhash: updating /var/lib/texmf/ls-R-TEXMFLIVEDIST...
  texhash: updating /var/lib/texmf/ls-R...
  texhash: 
  done. 

However, I cannot compile this file:

  /documentclass{article}
  /usepackage{fontspec}
  /setmainfont{Linux Libertine 0} 
  /begin{document}
  test
  /end{document}


  (/usr/share/texlive/texmf-dist/tex/latex/base/fontenc.sty
  ! Font \TU/lmr/m/n/10=[lmroman10-regular]: +tlig; at 10pt no
