Topic - What is Linux Kernel and How to upgrade to Linux stable kernel 3.18.1


What Is Linux Kernel?

Those who don't know what is the Linux Kernel they should know it because Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.

Latest Stable Linux Kernel Version 3.18.1
It's been a quiet week, and the patch from rc7 is tiny, so 3.18 is out.
I'd love to say that we've figured out the problem that plagues 3.17 for a couple of people, but we haven't. At the same time, there's absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn't make sense. Especially since
that would just have then held things up entirely over the holiday break.
So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that "Ahaa" moment) over the next week. But in solidarity with Dave (and to make my life easier too let's try to avoid introducing any _new_ nasty issues, ok?]

The best thing to do is to use stable repositories and run:

apt-get dist-upgrade

Of course you have to be root first or you can put sudo in front of the command. This may or may not give you this specific kernel, but you will get the latest and greatest stable release if all goes well in addition to upgrading all of you other software too.

Obviously, back up all your data first and make sure the process is not interrupted in any way whatsoever.

apt-get upgrade has different functionality. Although the files have issues will get updated if you want. Surely if you want to update kernel to 3.18.1 using apt-get upgrade then do. If you only want to upgrade to any particular kernel then using this method is handy.
