Ubuntu 15.04 and Skype installation problem (Cannot install libqtwebkit4:i386)

I upgraded my Ubuntu to newest version (15.04) and all worked fine excepts Skype.

When I was trying install Skype I had message from console:

Cannot install libqtwebkit4:i386

I spent some time on looking for best solution with missed dependencies, but finally I found where was problem.

If you have similar problem try this:

$ sudo dpkg --add-architecture i386
$ sudo apt-get update

Next go to directory /etc/apt/sources.list.d and find file like ondrej-phpX-trusty.list (X - version, in my case 5-5_6).

$ cd /etc/apt/sources.list.d
$ sudo gedit ondrej-php5-5_6-trusty.list

Remove comment from first ppa line (remove #). Save changes and type in console:

$ sudo apt-get update
$ sudo apt-get install skype

It should work, but if you have problems then write comment here.
