sfdisk doesn't work anymore?

I updated my OS to Ubuntu GNOME 15.10 but now I have a huge issue : sfdisk doesn't work! I really need it to build partitions on my SD cards for an embedded Linux but it seems that the options changed. How to do to keep it working? Here is the script I use : CARD_DEV=$1 unset LANG umount ${CARD_DEV}* >& /dev/null if [ -b "$CARD_DEV" ] ; then echo "*************** Formatting SD card... ***************" dd if=/dev/zero of=$CARD_DEV bs=1024 count=1024 SIZE=fdisk -l $CARD_DEV | grep Disk | awk '{print $5}' echo DISK SIZE - $SIZE bytes CYLINDERS=echo $SIZE/255/63/512 | bc echo CYLINDERS - $CYLINDERS { echo 1,9,0x0C,* echo 10,,,- } | sfdisk -D -H 255 -S 63 -C $CYLINDERS $CARD_DEV mkfs.vfat -F 32 -n "boot" ${CARD_DEV}1 mke2fs -j -L "filesystem" ${CARD_DEV}2 fi And I get : sfdisk: invalid option -- 'D' sfdisk [options] [[-N] ] sfdisk [options] Display or manipulate a disk partition table.
