Didn’t work for me. After using this script: ```auto chmod 777 -R ./PYNQ/* ``` I get this errors: ```auto chmod: changing permissions of './pynq/lib/_pynq/_video/bsp/gpio': No such file or directory chmod: changing permissions of './pynq/lib/_pynq/_video/bsp/vtc': No such file or directory ``` and this error still remains: ```auto Tar: cannot hard link to ‘crosstool-ng-1.24.0.tar.bz2’ ``` ---

@Reza_Mashayekhi BTW did you use “sudo” when changing the right? I will suggest check alignment between the Vivado and the Ubuntu and the toolchain version. Too little info ---

My problem was solved by changing PYNQ directory. I was using virtual machine to run Ubuntu. PYNQ folder was inside `/mnt` which was sharing with Window. By changing PYNQ directory to `/home`, problem was solved. ---
