Well, after googling a little about that, i've removed/purged all the kernel packages but image & run dpkg-reconfigure -a & reboot. Then i've tried to install the new kernel again, and the error have gone.
So, dont know the reason but during the first installation process i've seen that was because of a "followup previous error". Which one ?
