As the title states, running the script generates a permission error for chmod,

Choosing a different location inside the local users folder generates the same error

Running the script with sudo stops the script asking you to run it as a local user.

Tried opening Ubuntu normally and with administrative privileges inside windows

Any idea what could cause this?

running the chmod command with sudo does work after the script failed. However, restarting the script re-executes the copy and the chmod command causing it to fail again
