I have an Ubuntu 13.10 installation, and some I must have removed some Packages or Repositories, so there are some packages which just do not want to install. Namely that is:
SKYPE
sudo apt-get install skype-bin
The following packages have unmet dependencies:
skype-bin:i386 : Depends: libqtgui4:i386 (>= 4:4.8.0) but it is not going to be installed
Depends: libqtwebkit4:i386 (>= 2.2~2011week36) but it is not going to be installed
Depends: libx11-6:i386 but it is not going to be installed
Depends: libxext6:i386 but it is not going to be installed
Depends: libxss1:i386 but it is not going to be installed
Depends: libxv1:i386 but it is not going to be installed
Depends: libgl1-mesa-glx:i386 but it is not going to be installed
Recommends: sni-qt:i386 but it is not going to be installed
Recommends: libasound2-plugins:i386 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Than nspluginwrapper
The following packages have unmet dependencies:
nspluginwrapper : Depends: nspluginviewer (= 1.4.4-0ubuntu5)
E: Unable to correct problems, you have held broken packages.
And a whole lot of other packages appear if I try to install the shown dependencies. I guess I have delete a whole repository, but how can I figure out which ones are be default in the list?
Thanks in Ahead!

here is a copy of /etc/apt/sources.list
