hddtemp doesn't work with NVMe drive

[psl]

Ubuntu 18.04.5 (Linux Mint 19.3)
hddtemp 0.3-beta15-53, amd64

I see that hddtemp tool cannot work with NVMe (SSD disk).
I test with WD "Blue" SN550 - 1TB, NVMe drive.

$ sudo hddtemp /dev/nvme0
ERROR: /dev/nvme0: can't determine bus type (or this bus type is unknown)

$ sudo hddtemp /dev/nvme0n1
ERROR: /dev/nvme0n1: can't determine bus type (or this bus type is unknown)

hddtemp can report temperature of my SATA drives:

$ sudo hddtemp /dev/sda /dev/sdb
/dev/sda: CHN-25SATAC3-120: 40°C
/dev/sdb: WDC WD5000AAKX-75U6AA0: 41°C

================================================

Utility `smartctl` reports temperature of NVMe drive:

$ sudo smartctl -iA /dev/nvme0
smartctl 6.6 2016-05-31 r4324 [x86_64-linux-5.0.0-32-generic] (local build)

Status changed to 'Confirmed' because the bug affects multiple users.

[Herbert Nees (f0rd-prefect)]

There is already a patch for hddtemp-0.3-beta15 on bugzilla@redhat (Red Hat Bugzilla – Bug 1801116, https://bugzilla.redhat.com/show_bug.cgi?id=1801116).

Please provide this enhancement on ubuntu, too. Thanks!

[Herbert Nees (f0rd-prefect)]

There is a fork already providing support for nvme drives and other enhancements: hddtemp v0.4.3 at https://github.com/vitlav/hddtemp (33 commits ahead),
invoke with sudo hddtemp /dev/nvme0n1

I just don't understand why the ubuntu repo cannot have the updated version 0.4.3 as a dep package... Still need to compile that to be able to use...
