Install Skype on Ubuntu 12.04 LTS 64-bit

A combination of Gx1sptDTDa and Alejandro García Seco worked perfectly for me.

1. Open terminal (Ctrl+Alt+T).

2. Copy and paste this into terminal:

   sudo apt-get install libqt4-dbus:i386 libqt4-network:i386 libqt4-xml:i386 libqtcore4:i386 libqtgui4:i386 libqtwebkit4:i386 sni-qt:i386
   

   Press Enter.

3. Then install Skype by pasting this:

   sudo apt-get install skype
   

Skype 4.2 is running on my fresh Ubuntu 12.04 LTE 64bit.

>> 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.
