    Unable to get device for partition 1 on device /dev/mmcblk0

    Hi guys. When I try to install PVE on my device I get the error "Unable to get device for partition 1 on device /dev/mmcblk0". I've tried selecting ext4, xfs and zfs, but nothing worked. I'm installing from a 16GB USB 3.0 and the device is a Teclast TbooK 16 Power with a 64GB Samsung eMMC...
