As you may know, there is no official WhatsApp client for Desktop operating systems, Linux and Windows included. But now, a third party solution has been found.

But recently, a third party developer has created an unofficial WhatsApp client based on the WhatsApp web service.
Main features of WhatsApp for Desktop:
- Group chats
- Send photos & videos
- Share locations
- Native notifications
- Open links in browser or new window
- Multi-platform. Supports Linux, Windows
Because this is a WhatsApp Web wrapper, you need to keep your phone connected to the internet, in order to use WhatsApp. Also, support for performing audio calls is not available, the web service lacking this service also.
Installation instructions:
The easiest way to install the unofficial WhatsApp client on your Ubuntu, Debian or derivative system like Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, SparkyLinux, Robolinux etc, is to download the deb package for your system’s architecture (i386 for 32 bit OSes and amd64 for 64 bit systems) and install it via command-line:
Install WhatsApp for Desktop on 32 bit Ubuntu, Debian and derivative systems:
$ sudo apt-get install gdebi
$ wget https://github.com/Aluxian/WhatsApp-Desktop/releases/download/v1.1.0/UnofficialWhatsApp_linux32.deb
