I have tried to find some PPA's for Ubuntu 14.04 but didn't find any. So I tried to install the package for previous releases, with no luck and a lot of dependencies issues.

There isn't sopcast for 14.04 at any PPA's at this moment but I found a working and easy to understand advice at http://mauriziosiagri.wordpress.com/tag/sopcast/ .
Although it's written for 13.10, it works for 14.04 too.
From my experience, you should first install pythong-glade2, otherwise there will be an minor error which won't effect running the program -- but annoying .
sudo apt-get install python-glade2
It's a good idea to note down step by step what you do incase you should have problem installing it ( I hope you won't).
