核心问题似乎是找不到字体LibertinusSans-BoldOblique。
在终端中运行fc-list | grep -i libertinus效果如下：

但fonts使用lm或者times没有问题。

环境信息：

操作系统：Ubuntu 20.04 focal(on the Windows Subsystem for Linux)
TeX工具： Texlive 2020 (full installation)

[stone-zeng]

libertinus-otf 在后续版本删掉了 LibertinusSans-BoldOblique.otf 等几个字体文件。临时的解决方法是在导言区加上

\expandafter\def\csname g__fdu_font_style_libertinus_bfsl_tl\endcsname{Bold}

把粗斜版本重定向到粗（当然这样也就没有粗斜了，不过粗斜的无衬线体应该很少用到）。

[YijunYuan]

Maybe we can try something like

\setsansfont[AutoFakeSlant,AutoFakeBold]{LibertinusSans-Regular.otf}

AutoFakeSlant is not so perfect, but it's a kind of temporary solution.

(The above line of code is just a demonstration.)
