Mellanox Virtual Card Temperature Value not displayed ERROR

[tonyabc]

Expected behaviour

The Mellanox Range of Network Adapters have a temperature sensor that outputs it's value in Centigrade and displays using the Sensors command successfully. The sensor is detected in Mate-Sensors-Applet as "Temp1" variable and selecting it should generate a corresponding value on the panel.
Sensors output
mlx5_0000:a2:00.0-virtual-0 Adapter: Virtual device temp1: +41.0°C

Actual behaviour

When the "Temp1" variable is selected in the mate-sensors-applet preferences selection list, instead of producing a value it instead produces an ERROR flag and in notifications "Error updating sensor Temp1 - An error occurred while trying to update......" notification. Hovering over the ERROR flag in the panel shows "Temp1 - error compiling URL regex : Not Match"

Steps to reproduce the behaviour

Install Mellanox card, select Temp1 variable relating to value in mate-sensors-applet preferences.

There may be more than one TEMP1 in mate-sensors applet with your install, and it's been so long since the way the applet interacts with libsensors has been updated that this list is often totally different that what running sensors shows. I have one of several "TEMP3" values as my CPU temp, it matches k10temp-pci-00c3 and either Tctl or Tccd1 nmot sure which as they are so close. It's a LOT of trial and error with varying CPU and GPU loads to get this right on setting the applet up anew.

Look through every temp value the applet offers for one matching the output from
mlx5_0000:a2:00.0-virtual-0 Adapter: it's a good chance that's the right one.

Hi

It's the correct sensor as the notification popup actually states that it's the mlx5 adapter that's erroring.
