How to Install Python 3.6.1 in Ubuntu 16.04 LTS

Last updated: December 23, 2017

This quick tutorial is going to show you how to install the latest Python 3.6.1 in Ubuntu 16.04 LTS via PPA.

Ubuntu 16.04 comes with both Python 2.7 and Python 3.5 by default. You can install Python 3.6 along with them via a third-party PPA by doing following steps:

1. Open terminal via Ctrl+Alt+T or searching for “Terminal” from app launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:jonathonf/python-3.6

Type in your password (no visual feedback due to security reason) when it asks and hit Enter.

2. Then check updates and install Python 3.6 via commands:

sudo apt-get update

sudo apt-get install python3.6

Now you have three Python versions, use python command for version 2.7, python3 for version 3.5, and/or python3.6 for version 3.6.1.

3. To make python3 use the new installed python 3.6 instead of the default 3.5 release, run following 2 commands:

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Finally switch between the two python versions for python3 via command:

sudo update-alternatives --config python3

After selecting version 3.6:

python3 -V

UPDATE: due to this bug, gnome-terminal won’t launch after step 3, a workaround is running following commands to recreate the symlink:

sudo rm /usr/bin/python3

sudo ln -s python3.5 /usr/bin/python3

Fix Terminal Shortcut & PrintScreen Key Delay in Ubuntu 16.04

Last updated: July 5, 2017

I’ve been running into desktop shortcut key issue recently in my Ubuntu 16.04 LTS. When I trying to launch a terminal or take a screenshot, there will be more than 20 seconds delay after pressing Ctrl+Alt+T or PrintScreen on keyboard.

This happened after installed some Gnome related application libraries. And I found this BUG after doing a little search. A workaround is to restart the gnome-keyring-daemon service.

1. Launch terminal from Unity Dash, Gnome launcher, or other app launcher.

When it opens, run command to kill the service:

sudo killall gnome-keyring-daemon

The service starts automatically after you killed it, and that fixes the shortcut delay issue until reboot.

2. Until Gnome Team fixed the issue, you have to run the command automatically on startup by doing following steps:

Launch Startup Applications utility, click Add button and type:

  • Name: whatever
  • Command: killall gnome-keyring-daemon
  • Comment: whatever

Finally click Add the startup item and enjoy!

How to Install Linux Kernel 4.12 in Ubuntu / Linux Mint

Last updated: July 3, 2017

Linux Kernel

The 4.12 Linux Kernel was finally released earlier today. Linus Torvalds announced in lkml.org:

Things were quite calm this week, so I really didn’t have any real reason to delay the 4.12 release.

As mentioned over the various rc announcements, 4.12 is one of the bigger releases historically, and I think only 4.9 ends up having had more commits. And 4.9 was big at least partly because Greg announced it was an LTS kernel. But 4.12 is just plain big.

There’s also nothing particularly odd going on in the tree – it’s all just normal development, just more of it that usual. The shortlog below is obviously just the minor changes since rc7 – the whole 4.12 shortlog is much too large to post.

In the diff department, 4.12 is also very big, although the reason there isn’t just that there’s a lot of development, we have the added bulk of a lot of new header files for the AMD Vega support. That’s almost exactly half the bulk of the patch, in fact, and partly as a result of that the driver side dominates everything else at 85+% of the release patch (it’s not all the AMD Vega headers – the Intel IPU driver in staging is big too, for example).

But aside from just being large, and a blip in size around rc5, the rc’s stabilized pretty nicely, so I think we’re all good to go.

Go out and use it.

Kernel 4.12 top features:

  • initial GeForce GTX 1000 series 3D accelerated support on Nouveau driver stack
  • Intel’s DRM driver has turned on atomic mode-setting by default
  • Initial Radeon RX Vega support on AMDGPU DRM driver
  • A USB Type-C port manager
  • KASLR enabled by default for x86 systems.
  • BFQ and Kyber now mainline as two new I/O schedulers.
  • Continued power management tuning.

How to Install Kernel 4.12 in Ubuntu / Linux Mint:

The mainline kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use.

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

Download Kernel 4.12 (.deb)

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

  1. linux-headers-4.12.0-xxxxxx_all.deb
  2. linux-headers-4.12.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-image-4.12.0-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 4.12 from the command console, run the commands below one by one:

For 64-bit OS:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-headers-4.12.0-041200_4.12.0-041200.201707022031_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-headers-4.12.0-041200-generic_4.12.0-041200.201707022031_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-image-4.12.0-041200-generic_4.12.0-041200.201707022031_amd64.deb

sudo dpkg -i *.deb

for 32-bit OS:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-headers-4.12.0-041200_4.12.0-041200.201707022031_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-headers-4.12.0-041200-generic_4.12.0-041200.201707022031_i386.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-image-4.12.0-041200-generic_4.12.0-041200.201707022031_i386.deb

sudo dpkg -i *.deb

After installed these .debs, restart and enjoy!

Uninstall Linux Kernel 4.12:

Start/restart your machine and select boot with the previous kernel in Grub2 -> Advanced menu. Then use Ubuntu Tweak, or other system tool to remove the Kernel 4.12, or you may see this how to remove old kernels tutorial.
