mtxdoc.sty in texlive-music

[Lippolis Giuseppe]

I'm compiling a latex file (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwiax72KxdCCAxUpgP0HHW2ADR0QFnoECBgQAQ&url=https%3A%2F%2Fctan.math.washington.edu%2Ftex-archive%2Fsupport%2Fm-tx%2Fdoc%2Fmtxdoc.ltx&usg=AOvVaw0G5ert5C3-XAwfcEbkoRI9&opi=89978449) using pdflatex.
During the compilation I got this error:

! LaTeX Error: File `mtxdoc.sty' not found.

Type X to quit or <RETURN> to proceed,

The "mtxdoc.sty" is actually present in texlive-music package and I found it in /usr/share/doc/texlive-doc/generic/m-tx/mtxdoc.sty but texlive is unable to find it.

my configuration:
lsb_release -rd
Description: Ubuntu 22.04.3 LTS
Release: 22.04
