Using xubuntu 18.04, it appears that /dev/nvme0 is not supported, unless it requires root access, maybe i should boot a live usb and enable root gui and test it...

I have the same problem 
/dev/nvme0 is not showing any data and I can get data properly from /dev/dm-1 
It would be great to get data from nvme too

nvme devices don't seem to be supported, which is a significant issue now they are the storage in many laptops.

It is working fine with a NVMe SSD, because they are just a block device like any other hard drive. You have to use /dev/nvme0n1 instead of /dev/nvme0.
Comment 5 pqwoerituytrueiwoq 2019-05-10 01:13:10 CEST
Confirming that /dev/nvme0n1 does infant work
Why do I have to define a specific partition and not the drive itself that is like using /dev/sda1 instead of /dev/sda
Comment 6 Anonymous 2019-05-10 21:01:11 CEST
That is the way NVMe was designed, as a device can contain multiple namespaces (read as "storage areas"). /dev/nvme0 is a *character* device representing the first NVMe device, while /dev/nvme0n1 is a *block* device representing the first namespace on said device, and /dev/nvme0n1p1 is a *block* device representing the first partition in said namespace. /dev/nvme0n1 is the NVMe equivalent to hdd's /dev/sda.

$ ls -l /dev/sda* /dev/nvme*
crw------- 1 root root 243, 0 May 10 20:40 /dev/nvme0
brw-rw---- 1 root disk 259, 0 May 10 20:40 /dev/nvme0n1
brw-rw---- 1 root disk 259, 1 May 10 20:40 /dev/nvme0n1p1
brw-rw---- 1 root disk   8, 0 May 10 20:40 /dev/sda
brw-rw---- 1 root disk   8, 1 May 10 20:40 /dev/sda1
