That's not good.
Especially we do not have to show up at grub-devel as long as the test
USB stick might have problems as storage device.

That's normal with Debian ISOs for "i386" and "amd64". The first partition
marks the whole ISO.


But the checksum should really match the one of the ISO image file and
the one listed in the *SUMS file.
Please verify that your ISO image file yields the checksum that is listed
in *SUMS.

Does the checksum of partition 1 (or truncated base device) match *SUMS ?


Have a nice day :)
