Tar: cannot hard link to 'crosstool-ng-1.24.0.tar.bz2'

@Reza_Mashayekhi

I guess you did not read the previous reference:

The setup guide is very clear and mentioned @ 3A step
STEPS:

  1. I will suggest download 18.04.06 LTS Ubuntu from official website
  2. Create a virtual disk size about 200GB or more, set the CPU >#4, RAM >#8192
  3. 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~
