Mm. I suspect part of your problem is that you're not actually using Unity, are you.....or even Ubuntu, come to that. (Remember, Unity is/was an Ubuntu 'exclusive'. Just like Ubuntu One was. And Ubuntu Phone. And.....well, I could go on. But I won't.)
AFAICT, you're using Mint. With the MATE desktop. (Which is a far more sensible choice, anyway. Unity was.....peculiar, to say the least.)
I've remembered that I do in fact have pSensor running in one of my Pups.....Tahrpup64 6.0.5. But I don't use it for the temp readout, in any case; I have Mick Amadio's 'pmcputemp' and gKrellM for that. I mainly use it to monitor the HDD/SSD temps.
I vaguely recall not being able to get the tray temp readout in Mint Cinnamon. I think it would work in the old GNOME2.....and I know it worked in ZorinOS, a few years ago. It's one of those items that wasn't compatible with every desktop manager out there.....
The same goes for 'My-Weather'. (Another one I used to like using.)
