Where to download specific kernel headers?

I am new to Linux kernel module programming. How do I download and install the module-init-tools package?

• Just to make sure that I have all the correct tools installed, I ran the command "$depmod -v" following a documentation. Instead of the version number, I got a big log of warnings (or maybe, errors). Part of it looked like this: /lib/modules/3.13.0-24-generic/kernel/net/appletalk/appletalk.ko needs "unregister_snap_client": /lib/modules/3.13.0-24-generic/kernel/net/802/psnap.ko depmod: ERROR: openat(/lib/modules/3.13.0-24-generic, modules.dep.tmp, 1101, 644): Permission denied To fix the problem, I thought of downloading and installing the module-init-tools package. But I can't figure out how to go about it as I am new to Ubuntu. Kindly guide me on this. Also, is there any other way of solving this problem?

• Answer:

  You have to make sure that linux-headers are installed in your system. Secondly use sudo for all the administrative commands. Permission denied error reasons could be, you are not using sudo. Let me know, if you face anymore issues. Best of Luck!
