The bit about "held broken packages" is not reassuring. Did you try "apt-get -f install" yet? (If it wants to remove things you don't want removed, say no.) If that doesn't fix it, show us the output of these commands: apt-cache policy apt-cache policy php5-sybase apt-cache policy libsybdb5 cat /etc/apt/sources.list My suspicion is that you've got an incomplete or inconsistent sources.list which is somehow trying to pull php5-sybase from jessie, but libsybdb5 from somewhere else.
