We recently had a bug logged against our snap asking if it could read temperature data from the system. The denial looks like this:
Jan 5 11:35:31 ubuntunextcloud kernel: [1211761.978032] audit: type=1400 audit(1672918531.015:882155): apparmor="DENIED" operation="open" profile="snap.nextcloud.php-fpm" name="/sys/devices/virtual/thermal/thermal_zone0/type" pid=1855426 comm="php-fpm" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
A quick grep leads me to believe that snapd doesn’t have an interface that covers this, but I thought I’d ask the experts. Anyone know?

i’d expect this to be in system-observe or hardware-observe normally … if it is not covered in either of them it smells like a bug …
The issue persists on my Nextcloud 27.0.2snap1.

Describe the bug
In the system monitoring, no temperature is shown in the corresponding area.

Stale
Can it be resolved?

Other confined snaps such as btop and htop read and display temperature data correctly. A quick look at the btop yaml (https://github.com/aristocratos/btop/blob/main/snap/snapcraft.yaml ) suggests that this indeed resides in system-observe or hardware-observe. Not sure if libsensors is also needed for certain types of sensors.
