Linux Kernel

Linus Torvalds announced the final release of Kernel 4.10 days ago. He wrote on lkml.org:

So there it is, the final 4.10 release. It’s been quiet since rc8, but we did end up fixing several small issues, so the extra week was all
good.

On the whole, 4.10 didn’t end up as small as it initially looked. After the huge release that was 4.9, I expected things to be pretty
quiet, but it ended up very much a fairly average release by modern kernel standards. So we have about 13,000 commits (not counting merges – that would be another 1200+ commits if you count those). The work is all over, obviously – the shortlog below is just the changes in the
last week, since rc8.

Linux Kernel 4.10 release highlights:

  • Initial mainline GVT-g graphics virtualization support
  • Intel Turbo Boost Max 3.0 support.
  • EXT4 DAX iomap support and XFS iomap support.
  • Better Microsoft Surface 3/4 support. Wacom MobileStudio Pro class of drawing tablets support
  • Nouveau Boost support
  • More ARM platform support, better Raspberry Pi 3 support.
  • and many other changes.

How to Install Kernel 4.10 in Ubuntu:

The Ubuntu Kernel Team has made the DEB packages for the new kernel, available for download at the link below:

Download Kernel 4.10 (deb)

NOTE that Canonical does not support these Kernel packages. They are not appropriate for production use.

For the Desktop users, you can also use Ukuu a simple graphical tool to install the latest kernels.

For Ubuntu Server or those who prefer the command line, install them via following commands:

For 64-bit system:


cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-headers-4.10.0-041000_4.10.0-041000.201702191831_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-headers-4.10.0-041000-generic_4.10.0-041000.201702191831_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-image-4.10.0-041000-generic_4.10.0-041000.201702191831_amd64.deb

sudo dpkg -i *.deb

For 32-bit system:


cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-headers-4.10.0-041000_4.10.0-041000.201702191831_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-headers-4.10.0-041000-generic_4.10.0-041000.201702191831_i386.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-image-4.10.0-041000-generic_4.10.0-041000.201702191831_i386.deb

sudo dpkg -i *.deb

After installed these debs, restart and enjoy!

Uninstall:

To remove Linux Kernel 4.10, you may first restart and select boot with previous kernel (from Grub boot-loader -> Advanced Options) and then run command:

sudo apt-get remove linux-headers-4.10* linux-image-4.10*

Linux Kernel

Ubuntu 16.04.2 LTS was released 2 days ago with security updates, corrections for high-impact bugs, and hardware enablement stacks for use on newer hardware.

The LTS enablement stacks provide Linux Kernel 4.8 and newer X support, and they are included in the Ubuntu 16.04.2 desktop ISO images.

Ubuntu 16.04 LTS

For original Ubuntu 16.04, and Ubuntu 16.04.1 users, you have to manually install the HWE stacks. And below will tell you how:

How to Install Hardware Enablement Stacks:

Open terminal from app launcher or via Ctrl+Alt+T shortcut key. When it opens, run command:

sudo apt-get install --install-recommends xserver-xorg-hwe-16.04

Type in your password (no visual feedback) and hit Enter.

install hwe stack

After installation, reboot your computer.

How to Uninstall:

1. I don’t like the new X stack in my laptop, so I removed it via commands:

sudo apt remove xserver-xorg-core-hwe-16.04 xserver-xorg-input-all-hwe-16.04 linux-generic-hwe-16.04 xserver-xorg-video-all-hwe-16.04

You’ll see the command also removes the ubuntu-desktop package. Don’t worry. The following commands will install it back.

2. Then install back the original xserver-xorg via commands:

sudo apt install xserver-xorg-core

sudo apt install ubuntu-desktop xserver-xorg libgl1-mesa-dri:i386 libgl1-mesa-glx:i386

If you want to remove the new kernel 4.8, reboot and select boot with old 4.4 kernel (grub -> Advanced Options), then see this how to tutorial.

i2p-icon

i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client.

I2P (Invisible Internet Protocol) is a universal anonymous network layer. All communications over I2P are anonymous and end-to-end encrypted, participants don’t reveal their real IP addresses.

I2P client is a software used for building and using anonymous I2P networks. Such networks are commonly used for anonymous peer-to-peer applications (filesharing, cryptocurrencies) and anonymous client-server applications (websites, instant messengers, chat-servers).

I2P allows people from all around the world to communicate and share information without restrictions.

Features:

  • Distributed anonymous networking framework
  • End-to-end encrypted communications
  • Small footprint, simple dependencies, fast performance
  • Rich set of APIs for developers of secure applications

So far the latest version is ip2d 2.12 with following changes:

  • Additional HTTP and SOCKS proxy tunnels
  • Reseed from ZIP archive
  • ‘X’ bandwidth code
  • OpenSSL 1.1 for Android and Mac OS X
  • Some stats in a main window for Windows version
  • Fixed clock skew for Windows XP
  • New logo for Android
  • Reduced memory and file descriptors usage

How to Install i2pd via PPA in Ubuntu / Linux Mint:

The project offers DEB binaries for download in its release page.

For those who want to keep it up-to-date, install i2pd using the PPA repository via following steps:

1. Open terminal (Ctrl+Alt+T) and run command to add the PPA:

sudo add-apt-repository ppa:purplei2p/i2pd

Type in password (no visual feedback) when it asks and hit Enter.

i2pd-ppa

2. Then update package caches and install i2pd:

sudo apt update

sudo apt install i2pd

When a new release is out, simply launch Software Updater and upgrade it along with other system updates.

Uninstall:

You can remove the PPA anytime using Software & Updates utility under Other Software tab, and i2pd can be removed via command:

sudo apt remove i2pd && sudo apt autoremove
