I'm trying to install Ubuntu 18.04 Server on a native 4K SSD controller and it fails during the partition creation phase.

From the Installer I can see that the size detected for the disk is wrong, it is
showing 8 times the real size and try to use that size on the partition command for "/", I'm wondering if it is estimating the size based on 512B blocks instead of 4096B, but I couldn't find were this is happening. Anybody had a similar issue and know how to fix it?

From Install.log

    previous partition number for 'part-3' found to be '1'

    previous partition: /sys/class/block/nvme0n1/nvme0n1p1

    previous partition.size_sectors: 131072
