Sudo apt - cache search Linux - source see native Linux kernel source code is 3.13
But with the cat and the uname command is 4.40
Look under/user/SRC Linux - headers - 4.4.0-142, Linux - headers - 4.4.0-142 - generic

How much is the current kernel version?
Which 3.13.0 what version number,
I myself not changed in ubuntu kernel version

CodePudding user response:

Uname -r see is what you are currently running kernel version
Under the/usr/SRC/headers, kernels are not necessarily provided,

Specific use which kernel header file to compile the module, can through the/lib/modules/below correspond to the kernel version of the directory, there will be a soft link, build the soft connection usually point to the corresponding version of the kernel header files (if any)
