How to Install Kernel 4.16 in Ubuntu / Linux Mint

Last updated: April 2, 2018

Linux Kernel 4.16 was released yesterday. Linus Torvalds announced in lkml.org:

So the take from final week of the 4.16 release looks a lot like rc7, in that about half of it is networking. If it wasn’t for that, it would all be very small and calm.

We had a number of fixes and cleanups elsewhere, but none of it made me go “uhhuh, better let this soak for another week”. And davem didn’t think the networking was a reason to delay the release, so I’m not.

End result: 4.16 is out, and the merge window for 4.17 is open and I’ll start doing pull requests tomorrow.

Outside of networking, most of the last week was various arch fixlets (powerpc, arm, x86, arm64), some driver fixes (mainly scsi and rdma) and misc other noise (documentation, vm, perf).

The appended shortlog gives an overview of the details (again, this is only the small stuff in the last week, if you want the full 4.16 changelog you’d better get the git tree and filter by your area of interest).

Linux Kernel 4.16 release highlights:

  • Spectre / Meltdown mitigation & other security updates.
  • L2 CDP support for L2 cache partitioning on Intel CPUs
  • Correct AMD Zen temperature reporting for the Ryzen Threadripper 1900X processor.
  • P-State driver support for Skylake X servers.
  • POWER memory protection keys support
  • Oracle DAX driver for SPARC co-processor
  • Jailhouse guest support for non-root users

How to Install Kernel 4.16 in Ubuntu:

Other than using a graphical tool UKUU to install the latest mainline kernel packages, following steps will tell you how to manually download and install it in all current Ubuntu releases.

The mainline kernel PPA has made the new kernel binaries for Ubuntu, available for download at the link below:

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-4.16.0-xxxxxx_all.deb
  2. linux-headers-4.16.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-image-4.16.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

To get the Kernel 4.16 from the command console, run the commands below one by one:

For 64-bit OS:

cd /tmp/

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600_4.16.0-041600.201804012230_all.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-image-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb

sudo dpkg -i *.deb

for 32-bit OS:

cd /tmp/

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600_4.16.0-041600.201804012230_all.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600-generic_4.16.0-041600.201804012230_i386.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-image-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb
sudo dpkg -i *.deb

After installed these .debs, restart and enjoy!

How to Install Android Studio 3.1 Easily via Snap in Ubuntu

Last updated: March 30, 2018

Android Studio IDE 3.1 was released a few days ago. Here’s how to install it in Ubuntu 16.04, Ubuntu 17.10, Ubuntu 18.04 easily via Snap package.

Android Studio 3.1 introduced a C++ performance profiler for trying to analyze CPU bottlenecks in application code. It also adds lint checks for the Kotlin programming language, SQL code completion support, D8 is now the default Dex compiler, a new build output window, and other enhancements.

The community has built the IDE into snap, the universal Linux package format, that can be easily installed on all current Ubuntu releases.

1. For Ubuntu 14.04 and Ubuntu 16.04 users never installed a snap package, you need to install the snapd daemon while it’s not shipped by default in the two LTS.

Open terminal either via Ctrl+Alt+T or by searching ‘terminal’ from app launcher. When it opens, run command:

sudo apt-get install snapd snapd-xdg-open

2. Then launch Ubuntu Software, search for and install Android Studio.

For those who prefer command console, run command in terminal to install the snap:

snap install android-studio --classic

Once installed, launch the Android IDE from your application launcher (log out and log in back if you don’t see the app icon) and enjoy!
