Installing the Deb package available on the website doesn’t work for me. So I had to go find an alternative.
The following steps did work for me and I now have Viber running on my Ubuntu 14.04:
wget -O viber.deb http://download.cdn.viber.com/cdn/desktop/Linux/viber.deb
sudo dpkg -i viber.deb
sudo apt-get install -f
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-4.9
sudo apt install libstdc++6
