Install Skype on Ubuntu 12.04 LTS 64-bit

For 32Bit
Terminal Commands:

wget  http://download.skype.com/linux/skype-ubuntu-lucid_4.2.0.11-1_i386.deb
sudo dpkg -i skype-ubuntu-lucid_4.2.0.11-1_i386.deb
sudo apt-get -f install;rm skype-ubuntu-lucid_4.2.0.11-1_i386.deb

 

For 64Bit Terminal Commands:

sudo dpkg --add-architecture i386
sudo apt-get install ia32-libs
sudo apt-get update
wget http://download.skype.com/linux/skype-ubuntu-lucid_4.2.0.11-1_i386.deb
sudo dpkg -i skype-ubuntu-lucid_4.2.0.11-1_i386.deb
sudo apt-get -f install;rm skype-ubuntu-lucid_4.2.0.11-1_i386.deb

After all of this run in terminal sudo apt-get install sni-qt:i386; This will restore the skype contact window
That's all, work done in maximum 5 minutes. I use Ubuntu on 64bit and this method to install Skype worked always perfectly.
