Preliminary note: using something as old as lm-sensors 2.10.1 with
a kernel as recent as 184.108.40.206 doesn't make much sense IMHO. We do
our best to preserve compatibility but it's hard to always get it

The warning documented above is unrelated to your problem, this is

Shouldn't be. For one thing you should be able to install libsensors3
and libsensors4 in parallel. Once this is done you should be able to
upgrade lm-sensors (and only lm-sensors) from version 2.x to version
3.x. I am no Debian expert though, maybe I'm missing something.

Which modules are these?
Please provide the full output of sensors-detect.
Did this system ever work with a different combination of lm-sensors
version and kernel version? And what system is this?
