Hello Linux Geeksters. As you may know, Viber is a popular instang messaging application running on Android. Like WhatsApp, Viber has video calling functions and allows the users to easily send text messages and photos, without needing to register. The developers have decided to make the application available for desktop operating systems, including Windows, Mac OS X and Linux.
Unfortunately, the Viber native client for Linux works only on 64 bit systems, and so, in order to install Viber on 32 bit systems, we have to do that via Wine. 
If you already use Viber on your mobile phone, setting everything up is easy. All you have to do is enter your mobile number into the application, type in the authentication code you get to your mobile app and you’ll get all your Viber contacts available in the Linux client.
In this article I will show you how to install Viber on both 32 bit and 64 bit Ubuntu 14.04 Trusty Tahr, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Deepin 2014, LXLE 14.04, Peppermint Five, Linux Lite 2.0 and other Ubuntu derivative systems.
Follow the instructions for your system exactly, in order to get a successful Viber installation.
How to install Viber on 32 bit Ubuntu, Linux Mint, Deepin, Pinguy OS and Other Ubuntu derivative systems, via Wine:
Because there is no Viber package for 32 bit systems, we can only install the Windows version of Viber, via Wine.
$ sudo add-apt-repository ppa:ubuntu-wine/ppa
$ sudo apt-get update
$ sudo apt-get install wine1.7 winetricks
Download the Viber installer for Windows and install it, on Wine:
$ wget http://download.cdn.viber.com/cdn/desktop/windows/ViberSetup.exe
$ wine ViberSetup.exe
To remove Viber, type wine uninstaller in your terminal and uninstall the Vibe from the GUI.
How to install Viber on 64 bit Ubuntu, Linux Mint, Deepin, Pinguy OS and Other Ubuntu derivative systems, via Wine:
Viber is available for 64 bit (amd64) systems as a deb package, so installing it is easy. All you have to do is download the deb package from the official site:
$ wget download.cdn.viber.com/cdn/desktop/Linux/viber.deb
And install it via command-line. I prefer gdebi over dpkg due to the fact that it also handles dependencies:
$ sudo apt-get install gdebi
$ sudo gdebi viber.deb
Optional, to remove viber, do:
$ sudo apt-get remove viber
