Version First unspecified

If you're not sure this is actually a bug, instead post about it at
https://discuss.kde.org
I have discussed this at
<https://discuss.kde.org/t/kstatsviewer-no-sensors-available/40649> and did not
move closer to resolution.
I do not believe this to be a bug but rather some kind of misconfiguration or
missing packages. This display works as desired on Debian Trixie on a Raspberry
Pi. With the Raspberry Pi OS (derived from Debian) it does not work. I suspect
a misconfiguration or issue with `ksystemstats` and appreciate guidance from a
dev who can help to track down and fix the issue.
***
SUMMARY
Graphical elements on `System Monitor` do not populate. Textual elements seem
to be OK.
STEPS TO REPRODUCE
1. Open `System Monitor`
OBSERVED RESULT
Observe top two panes remain unpopulated. At the top there is a pnk banner
"This page is missing some sensors and will not display correctly." Clicking
"Fix" results in a popup where all fields have no option to select.
EXPECTED RESULT
Graphical elements populate with values for the running system.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Raspberry Pi OS based on Debian Trixie
KDE Plasma Version: 6.3.6
KDE Frameworks Version: 6.13.0
Qt Version: 6.8.2
Kernel: 6.12.47+rpt-rpi2712 (64 bit)
ADDITIONAL INFORMATION
RpiOS uses the Debian repos directly and adds its own repo for Pi specific
stuff like the kernel and some tools. Since the RpiOS engineers support their
own desktop, I suspect that the KDE/Plasma packages are all from the Debian
repos. The same versions of KDE/Plasma work as expected on pure Debian. An Arch
variant EndeavourOS experiences the same issue and under the covers, must be
using the RpiOS produced kernel since the Rpi folk have not upstreamed all of
the necessary fixes to run on the Pi 5. I suspect that there might be some
kernel setting that has been turned off and which makes the information used by
`System Monitor` not available.
I have reviewed https://bugs.kde.org/show_bug.cgi?id=442588 as symptoms are
identical. I tried running `ksystemstats --replace` and it never returns. I
also see:
```text
hbarta@rafiki:~ $ ps -ef|grep ksystemstats
hbarta 4789 1900 99 14:48 pts/1 00:01:08 ksystemstats --replace
hbarta 5094 5052 0 14:49 pts/3 00:00:00 grep --color=auto
ksystemstats
hbarta@rafiki:~ $
```
But I do not know if `ksystemstats` had been running before I tried to replace
it. At present it seems to be hanging and `System Monitor` still has no
graphical information.
