Is this due to the system?

Hi @945716994, thanks for reaching out!

NVIDIA A100

Is it a server or workstation grade A100? Also, is it in Multi-Instance GPU (MIG) mode?

I have the same problem, I was using my school's service featured with A100. And I found I cannot install the package egl and osmesa needed below.

sudo apt-get install libnvidia-gl-440-server

Because it's an LFS system, I cannot install any packages outside the module loading system.

Do you know how I can tackle this problem? I really appreciate any help you can provide.
