当我从 ubuntu 20.04 终端打开 matlab 时出现以下错误。
libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

系统使用内置英特尔显卡。请帮我解决这个问题。
更新：输出apt-cache policy libgl1-mesa-dri libgl1-mesa-dri:i386为
