Ridercup, you need to have UTM Firmware version v9.50010 or above. You can download it from ftp.astaro.com/UTM/v9/up2date/
If you're on v9.315-2, it should be the "u2d-sys-9.315002-350012.tgz.gpg" as the one you want.
You will then need to manually upload/import it to the UTM from the advanced tab of Management>Up2Date and then it will show up as an available firmware update.
Oh and a side note, you don't need to decompress it or unpack it all, just download it then upload the file from your downloads folder straight to the UTM.
Take note, features in 350 are not part of 317 and vice versa.
