sensors：No sensors found!Make sure you loaded all the kernel drivers you need.Try sensors-detect to

执行sensors命令：

~# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

记修复过程

1. 保证systemd-modules-load.service和kmod.service，注释/etc/modules文件中 coretemp 和nct6775

~# cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

2. 查找模块coretemp.ko，如果本机没有，就需要从其它机子拷贝过来

~# find /lib/modules/4.15.0-91-generic/kernel/drivers/ -name coretemp.ko
/lib/modules/4.15.0-91-generic/kernel/drivers/hwmon/coretemp.ko

3. 向内核加载模块coretemp.ko

~# insmod /lib/modules/4.15.0-91-generic/kernel/drivers/hwmon/coretemp.ko

4.再次执行命令

~# sensors
coretemp-isa-0000
