How to install or upgrade the Linux kernel in Ubuntu to 4.2

Linux Kernel 4.2 has been released. LinusTorvalds wrote on lkml.org: with such a small change this week, it seems that the release of Version 4.2 in the last week will not be a problem. Of course, there are several amendments, but it does not seem to require a delay of one week. So this is now, and the merge window of 4.3 is now open. I already have several merge requests waiting for processing. I will start to process them tomorrow and release them as appropriate. The short log from rc8 is small and has been attached. This

The Linux kernel 4.2 has been released. Linus Torvalds writes on lkml.org:

With such a small change this week, it seems that there should be no problem to release version 4.2 in the last week. Of course there are still several amendments, but it does not seem to require a week delay. So this is now, and the merge window of 4.3 is now open. I already have several merge requests waiting for processing. I will start to process them tomorrow and release them as appropriate. The short log from rc8 is small and has been attached. This patch is also small...

 

What are the improvements to the new kernel 4.2? :

• Rewrite intel x86 assembly code
• Support for new ARM boards and SoC
• Encrypt F2FS per-file
• AMDGPU kernel DRM driver
• Support for Radeon DRM-driven VCE1 Video Encoding
• Preliminary support for Intel's Broxton Atom SoC
• Supports ARCv2 and HS38 CPU Cores
• Added support for queue spin locks
• Many other improvements and drive updates.

 

How to download the 4.2 kernel in Ubuntu:

The download link of the Binary Package of this kernel version is as follows:

• Download the 4.2 kernel (. DEB)

First check your operating system type, 32-bit (i386) or 64-bit (amd64), and then download and install the software package in the following ways:

1. Linux-headers-4.2.0-xxx_all.deb
2. Linux-headers-4.2.0-xxx-generic_xxx_i386/amd64.deb
3. Linux-image-4.2.0-xxx-generic_xxx_i386/amd64.deb

After the kernel is installed, run it on the terminal (Ctrl + Alt + T)sudo update-grubCommand to update grub boot-loader.

If you need a low-latency system (for example, for recording audio), download and install the following package:

1. Linux-headers-4.2.0_xxx_all.deb
2. Linux-headers-4.2.0-xxx-lowlatency_xxx_i386/amd64.deb
3. Linux-image-4.2.0-xxx-lowlatency_xxx_i386/amd64.deb

For Ubuntu servers without graphic user interfaces, you can run the following command to capture and download them one by one through wget and install them through dpkg:

For 64-bit systems, run:

1. cd /tmp/
2. wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-unstable/linux-headers-4.2.0-040200_4.2.0-040200.201508301530_all.deb
3. wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-unstable/linux-headers-4.2.0-040200-generic_4.2.0-040200.201508301530_amd64.deb
4. wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-unstable/linux-image-4.2.0-040200-generic_4.2.0-040200.201508301530_amd64.deb
5. sudo dpkg -i linux-headers-4.2.0-*.deb linux-image-4.2.0-*.deb

For 32-bit systems, run:

1. cd /tmp/
2. wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-unstable/linux-headers-4.2.0-040200_4.2.0-040200.201508301530_all.deb
3. wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-unstable/linux-headers-4.2.0-040200-generic_4.2.0-040200.201508301530_i386.deb
4. wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-unstable/linux-image-4.2.0-040200-generic_4.2.0-040200.201508301530_i386.deb
5. sudo dpkg -i linux-headers-4.2.0-*.deb linux-image-4.2.0-*.deb

Finally, restart the computer to take effect.
