Failed to load the package list

I've been having problems installing programs from the Ubuntu Software Center, and each time i try to do so i am greeted with:
Failed to load the package list
The details of the problem are E:Malformed line 97 in source list /etc/apt/sources.list (dist), E:The list of sources could not be read., E:The package lists or status file could not be parsed or opened.

gksudo gedit /etc/apt/sources.list gives this output:

My immediate guess is that there's something up with the very end since that is what line 97 is, but anything given to help resolve this problem will be appreciated.
