Thanks for trying out the 6.0 builds.
It is a really huge release and we will be releasing new docs and guides in the next few days.
Can you update to the new build we uploaded today?
The specific problem with your error may be that the Trisul Probe does not contain eth0 ; to fix that login as Admin / Admin and then go to Context0 > Profiles > Adapters and set it to the correct name. This is the most likely cause.
