Would you please show the output of mount ?

Hello, same error on diet-pi while trying to copy from sdcard to an nvmessd

Command I ran

sudo wipefs --all --force /dev/nvme0n1
sudo dd if=/dev/zero of=/dev/nvme0n1 bs=1024 count=1
# Install rpi-clone.
git clone https://github.com/geerlingguy/rpi-clone.git
cd rpi-clone
sudo cp rpi-clone rpi-clone-setup /usr/local/sbin

# Clone to the NVMe drive (usually nvme0n1, but check with `lsblk`).
sudo rpi-clone nvme0n1

lsblk

root@orangepi3b:~/rpi-clone# lsblk

And output of mount

rpi-clone expects to have two partitions and /boot/firmware or /boot mounted to partition 1 and / to partition 2.

According your lsblk output diet-pi just uses one partition and that's not supported by rpi-clone.
