[XeTeX] Music symbols from LilyGlyphs in XeLaTeX

[P P Narayanaswami]

I want to insert a few Music symbols (defined in LilyGlyphs package) 
using XeLaTeX.
The followionmg MWE used to compile fine and get the symbols in Ubuntu 
18.04 (with TeXLive
running, using "sudo" command of Ubuntu).  But after upgrading to Ubuntu 
20.04, this are not working.
Here is the minimal example along with all the error mesages I get, when 
compiled in XeLaTeX.

\documentclass{article}
\usepackage{fontspec}
\usepackage{lilyglyphs}  %%% for musical symbol segno
\newcommand{\segno}{\large \lilyGlyph{scripts.segno}}
\begin{document}
\segno
\end{document}

I get several error messages of "missing .inp" such as  ! LaTeX Error: 
File `core/opticals.inp' not found  (about 16 of them).
Then I get the following error message:
     ! Undefined control sequence.
     \segno ->\large \lilyGlyph{scripts.segno}

What am I missing here, or what is going wrong here?
