strange error while I add/remove applications!

[AlgoMantra]

So I tried to install Epiphany browser and this is what I get:

*E: /var/cache/apt/archives/epiphany-browser_2.20.0-0ubuntu1_i386.deb: files
list file for package `libtheora0' contains empty filename*

It's actually more complicated now!! It also gave me a serious error about
dpkg,
saying libtracker-gtk0 had some list file missing before the error above
popped
up, but I couldn't copy that message.
