Also please be descriptive about the issue you're reporting, i.e: what you tried & what's the expected behaviour.

I think auto-cpufreq is trying to check if there is new updates occasionally and crash when there is less than ideal network connectivity (e.g. public WIFI with captive portal not yet approved by the network will result in time out) at that time and stops working properly (you can tell by running auto-cpufreq --stats that does not refresh) but systemctl status auto-cpufreq.service reports active and remains actually ineffective.

I believe this could be fixed by a combination of 2 methods (either or both):

• a. prevent the failure of the update check to propagate its failure state into its core functionality
• b. let it crash all the way so systemd will restart it on failure

Why I think this issue should be addressed

Laptops (which auto-cpufreq is enhancing the experience of) will meet frequent changes of the network stability as it tends to travel between places.
