Where is the system console? I just ran a python script in blender.

However it gave me an errror:

Python script failed, check the message in the system console.




I've searched online but i can't find the system console. I have two terminals open to the blender file already but it did not show any error message. 



I am using Ubuntu 19, with Blender 2,80
Here, Window, Toggle System Console 

But if you run on linux / mac perhaps you need to see if you run Blender from terminal usually from that you going to find the error
