Unity 300 Drive Firmware - File uploaded is incorrect format

Hello,

I have downloaded on the Dell support site (Drivers and downloads) the last Drive Firmware Package : "Unity-Drive-Firmware-V19RC-2021-11-30.tgz.bin.gpg", but the Unity300 don't accept the driver with the error message : " File uploaded is incorrect format ".

Also, the checksum are different. I think it is not the good file available on the Dell support site.
