Ubuntu Server with APC UPS: always 0 prior measurements #166

In my setup I am running a headless Ubuntu server 24.04 LTS connected to an APC UPS. Trying to run Auto Tune returns:

$ sudo powertop --auto-tune
modprobe cpufreq_stats failed
Loaded 0 prior measurements
Cannot load from file /var/cache/powertop/saved_parameters.powertop
File will be loaded after taking minimum number of measurement(s) with battery only 
RAPL device for cpu 0
RAPL Using PowerCap Sysfs : Domain Mask d

Devfreq not enabled
glob returned GLOB_ABORTED
Cannot load from file /var/cache/powertop/saved_parameters.powertop
File will be loaded after taking minimum number of measurement(s) with battery only 
Leaving PowerTOP

I tried calibrating and rebooting multiple times but Loaded 0 prior measurements remains. It also promotes for taking minimum number of measurement(s) with battery only but it is unclear on how to do so.

any help is greatly appreciated!
