I guess you did not read the previous reference:
The setup guide is very clear and mentioned @ 3A step
STEPS:
- I will suggest download 18.04.06 LTS Ubuntu from official website
- Create a virtual disk size about 200GB or more, set the CPU >#4, RAM >#8192
- Update Ubuntu packages before setting up the PYNQ
3b) Git clone the PYNQ to /home//PYNQ <------
3c) sudo chmod -R 777 ./PYNQ/*
So i guess the issue had resolved.
ENJOY~
