I installed "apt-sources-list", ver. 1.0.4-1pclos2013, and this additional listing /etc/apt/sources.list:
As you've done both, it's not a bad idea to open /etc/apt/sources.list, in root, and display what is in it, the "apt-sources-list", ver. 1.0.4-1pclos2013 being older than the latest list posted by pinoc
of additions to the sources.list.
We're a bit in the dark as to the Broken packages, if it is found that your sources.list is corrupted it can be simply erased and corrected.
During this time of syncing a whole new primary server, with the additional ones, a feature of Synaptic; "Fix Broken Packages" shouldn't be used. Not sure if you are aware there is such a function.
Basically checking that the sources.list is correct is first step.
