Hello
I do not understand this error

Code:

a@a-usb:~/Téléchargements/Ventoy-1.0.20/INSTALL$ sudo ./Ventoy2Disk.sh -i /dev/sdb

***********************************************************
*                Ventoy2Disk Script                       *
*             longpanda  admin@ventoy.net                 *
***********************************************************

Don't run Ventoy2Disk.sh here, please download the released install package, and run the script in it.
a@a-usb:~/Téléchargements/Ventoy-1.0.20/INSTALL$

Can you explain me ?
