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.
