Can not log in to Skype in Ubuntu

Skype 4.2 worked perfectly until this morning in my Ubuntu 12.04. It took me a while to make Skype work again. This is how it works.

Remove Skype 4.2

$ sudo apt-get remove skype

Get rid of old Skype configuration

$ rm -fR ~/.Skype 

Download Skype 4.3 from Skype's website (http://www.skype.com/en/download-skype/skype-for-computer/). From there I got

skype-ubuntu-precise_4.3.0.37-1_i386.deb

*Depending on your machine and time, you might get different version of Skype.
*I tried to apt-get update to get the latest Skype. However, it seems the apt list is not up to date at that time, I can get the latest Skype by that approach.

Then install Skype 4.3

$ sudo dpkg -i skype-ubuntu-precise_4.3.0.37-1_i386.deb

Hope it works for you  : )
