Unable to start stonefish in Ubuntu 21.04

[miquelmassot]

Hi!

I've followed the same steps to build and run stonefish and I've been able to package it in a docker container. The container works for machines with Ubuntu 22.04 out of the box, but I just found it does not in a Ubuntu 21.04 machine. This is the output in the console log:

process[stonefish_simulator-31]: started with pid [758]

The PC I am running it on has an NVIDIA RTX 2070 with 8Gb graphics memory.
This is the output of nvidia-smi

and this is the output of glx-info

$ glxinfo | grep "OpenGL version"
OpenGL version string: 3.1 Mesa 21.0.3

Is there something I am missing? Is the issue with "OpenGL 4.3" being the minimum version supported?

Hello!
The last part shows the problem. Yes, it is required that the OpenGL version is 4.3 or higher. The question is why your OpenGL version is not correct, because for any modern GPU you will get OpenGL 4.6 support. You need to fix the driver installation or some docker settings? I have no experience with docker.
