What distro are you using? Based on the Segmentation fault, it seems like it’s crashing. I don’t know if the docker file will be helpful but we are pretty much downloading the ZIP, extracting it and starting the server for our image on Docker Hub.

The OS is CentOs 8, running in a LXD container.

Could you share the dockerfile?

Sure. Here you go:

Thanks Adam.
That works.

I will see what is up with the LXD, maybe I am missing some of the stuff you add :slight_smile:
