Well, it *should* work with a standard Debian kernel and applicable
hardware.

wooledg:~$ /sbin/modinfo coretemp

Your "No such device" error sounds like it probed for hardware and didn't
find any. If the module itself were missing from the file system, then
I would have expected "FATAL: Module coretemp not found in directory ...".

It says "Intel" in the description. Are you using an Intel CPU?

Here is the output of lscpu:

It looks like an FX8350 chip to me.

Comments appreciated
