I'm having trouble running scripts in gem5 Full System Simulation.
I'm new to gem5 and I was following this tutorial: http://learning.gem5.org/book/part3/fs_config.html#running-a-full-system-simulation
I was trying to run gem5 in Full System Simulation passing a script in its parameters. The simulation starts normally, and it works if I don't pass any script parameter. However, whenever I pass any script in the parameters, in this case the same runscript that is present in the tutorial(test.rcS), I get the following error:

I've tried to run a simple mergesort C program in the exact same way and got the same problem. What should I do to fix this issue? Don't know if it's relevant, but i'm using Ubuntu 18.04.
