我正在尝试使用国家核研究机构包来编译文件，但我一直收到错误：
TraditionalBuilder: Engine: lualatex. Invoking latexmk... done.
Errors:
/usr/share/texlive/texmf-dist/tex/latex/newtx/newtxtext.sty:472: LaTeX Error: File `realscripts.sty' not found. [ \ifntx@KOMA]
No warnings.
我安装了并重新安装了十几个不同网站推荐的几乎所有软件包，但都无济于事。我正在运行基于 Ubuntu (22.04.2 LTS) 的系统，请问我该如何解决这个问题？
这个基本文件足以重现该问题：
