[Updated] Install Flash Player for Chromium, Opera in Ubuntu 16.10

Last updated: March 5, 2017

The Pepper Flash Player installer, pepperflashplugin-nonfree package, does not work any more for Chromium based browsers since Google Chrome 54 removed the latest PPAPI bundle.

failed to install PPAPI

There’s now a new Pepper flash installer available for Ubuntu 16.04, Ubuntu 14.04, that installs PPAPI directly from adobe website.

For those who want to install the latest PPAPI Flash Player (so far it’s 23.0.0.185), you can download the source tarball from Adobe website and install it manually.

1. Go to link below:

Download Adobe Flash (PPAPI)

Check your OS type from System Settings -> Details, then select in download page:

Linux (64-bit) or Linux (32-bit)
FP 23.0 PPAPI

2. Extract the downloaded .tar.gz package, and navigate to the result folder.

3. pepperflashplugin-nonfree is still required to work as a wrapper. Install it if you don’t have it via command (Press Ctrl+Alt+T to open terminal):

sudo apt install pepperflashplugin-nonfree

4. Now move the libpepflashplayer.so file from downloaded folder to /usr/lib/pepperflashplugin-nonfree directory.

You can do this via command:

sudo mv ~/Downloads/flash_player_ppapi_*/* /usr/lib/pepperflashplugin-nonfree/

Or open the “/usr/lib/pepperflashplugin-nonfree” directory via root by running command:

gksudo nautilus /usr/lib/pepperflashplugin-nonfree

Then drag and drop ALL THE FILES from Downloads folder to the directory:

Finally restart Chromium, Opera, or other based browsers and flash should work.

Install Wunderlist App ‘Wunderlistux’ in Ubuntu 16.04, Elementary OS

Last updated: October 21, 2016

Wunderlistux is an open-source electron wrapper for the free Wunderlist task management software, that is specially designed for Elementary OS.

The app uses the elementary (sic) GTK theme and icons and looks awesome indie in elementary OS Loki. It also works in Ubuntu 16.04 in my test though it lacks application icon.

How to Install Wunderlistux in Ubuntu / Elementary OS (64-bit only):

Download the source (.zip or .tar.gz) from the link below:

Wunderlist release page

Extract and run the executable from the result folder will launch the software:

To install an application shortcut:

1. Open terminal (Ctrl+Alt+T) and run command to open the source tarball via root:

gksudo file-roller ~/Downloads/wunderlistux-0.0.4-linux-x64.tar.gz

Change the package name “wunderlistux-0.0.4-linux-x64.tar.gz” in the code to yours. And install gksu via command sudo apt install gksu if need.

When the source opens via Archive Manager, do:

rename the source folder to wunderlistux
extract it to other location -> Computer -> /opt/

So finally you installed Wunderlistux into /opt for global use:

2. Now run command to create a shortcut file:

gksudo gedit /usr/share/applications/wunderlistux.desktop

When the file opens, paste below lines and save it.

[Desktop Entry]
Name=Wunderlistux
Exec=/opt/wunderlistux/Wunderlistux
Terminal=false
Type=Application
Icon=/opt/wunderlistux/resources/app/images/wunderlist.png

Now you should be able to launch the software from Unity Dash or Application Launcher. Enjoy!

(Optional) If you want to remove Wunderlistux, simply remove the .desktop file and source folder from /opt via command:

sudo rm -rf /opt/wunderlistux && sudo rm -rf /usr/share/applications/wunderlistux.desktop

How to Create A Bootable Ubuntu 16.10 USB Stick

Last updated: October 14, 2016

Ubuntu 16.10 Yakkety Yak has been released. For those want to install Ubuntu 16.10 from an ISO image, here’s how to create a bootable USB stick using UNetbootin.

Unetbootin is an open-source and cross-platform utility for burning ISO into a bootable USB stick. And I use UNetbootin to install Ubuntu since it was Ubuntu 9.04 Jaunty.

Requirements:

A computer with Linux, Windows, or Mac system.
USB drive with 2GB+ memory.

To get start:

1. Download UNetbootin executable from the link below:

Download UNetbootin

For Ubuntu, you don’t have to download anything, just search for and install unetbootin from Ubuntu Software Center.

2. Download Ubuntu 16.10 ISO image from releases.ubuntu.com/yakkety

You may check the downloaded image via MD5SUMS or SHA1SUMS

3. Plug-in your USB drive (better to format to FAT32) and then launch UNetbootin:

It auto-detects and selects your USB drive, so all you need to do is check the “Diskimage” box and choose the Ubuntu 16.10 ISO image. And leave other options default.

4. Click OK and it starts copying files to the USB stick and this will take a few minutes:

5. When done, it prompts you to restart or exist:

Finally plug the USB drive to any computer, select boot USB in BIOS settings, and you’ll see the GRUB menu, when it boots up, with boot entries to try, install Ubuntu.

ANGRYsearch – Everything Like Search Utility for Ubuntu Linux

Last updated: October 10, 2016

Looking for a Linux version of Everything Search Engine? ANGRYsearch helps you find files and folders rapidly in Linux with a simple graphical interface.

Linux file search, instant results as you type
Attempt at making Linux version of Everything Search Engine because no one else bothered.
Everyone seems to be damn content with searches that are slow, populating results as they go; or are cli based, making it difficult to comfortably make use of the results; or are heavily integrated with a file manager, often limiting search to just home; or are trying to be everything with full-text file’s content search.

ANGRYsearch is written in Python3 and PyQt5. It’s database can be set to two different modes in ~/.config/angrysearch/angrysearch.conf file with angrysearch_lite being set to true or false:

lite mode (Default) shows only name and path
full mode shows also size and date of the last modification, the drawback is that crawling through drives takes roughly twice as long since every file and directory gets additional stats calls

There are also 3 search mode available:

Fast mode (Default) extremely fast, but no substrings, meaning it would not find “Pirates” or “Whiplash“, but it would “Pirates” or “The-Fifth”
slow mode – enabled when the checkbox is unchecked, slightly slower but can find substrings
regex mode – activated by the F8 key, indicated by orange color background
slowest search, used for very precise searches using regular expressions, set to case insensitive

How to install ANGRYsearch in Ubuntu:

Install ANGRYsearch is quite easy since the source tarball includes a installer.sh script:

1. Download the source from the link below:

Download ANGRYsearch

2. Extract and open the result folder in terminal:

for ubuntu 14.04 you need to install nautilus-open-terminal and restart nautilus

3. When the terminal windows opens, run command to make execute and run the installer:

chmod +x install.sh && sudo ./install.sh

Type in your password when it asks and hit Enter.

Once installed, launch ANGRYsearch from Unity Dash or App Launcher, when it opens, click update to index your Linux files/folders, and mounted Windows partitions.

Uninstall ANGRYsearch:

Although the source does not offer an uninstall script, you can run the utility via command:

sudo rm -r /usr/share/angrysearch /usr/bin/angrysearch /usr/share/applications/angrysearch.desktop
