Tried to use skype on ubuntu 14.04, and did not work, here is how I fixed it

I use ubuntu 14.04. And I tried to use skype there. not working.
There was a skype there. And I could not sign in. I used microsoft account to log in.
I uninstalled that skype.
And I downloaded a skype rpm from here
https://www.skype.com/en/get-skype/

And I installed the rpm:

sudo apt-get install alien dpkg-dev debhelper build-essential

sudo alien packagename.rpm

sudo dpkg -i packagename.deb

it finally works.
