your sources.list  is sane.

Do you have any file in `/etc/apt/sources.list.d' ?

PPA stuff is foreign to Debian: at one point some ubuntu material was introduce either by you
or somewhere else (in thsi case, it is a bug).
Ubuntu is build upon Debian, and bring its own stuff and policy. It is also more oriented
to regular user. But coming from Fedora, I guess that you are familiar with UN*X.

I would forget synpatic and use the command interface tools: aptidute(1), or better apt(1)
(along sudo  or as root). I am not a fan of graphical interfaces.
