Repository probleme on Mint 17.2

Hi, I got this probleme on mint 17.2 cinnamon and i deleted the repository adress and put this one:
deb http://apt.insynchq.com/mint/dists/rafaela/non-free/binary-amd64/Packages
I get the same message, it fail…

Some index files failed to download. They have been ignored, or old ones used instead.

And the update manager say this:

E:malformed line 1 in source list/ect/apt/sources.list.d/additional-repository.list (dist)

Wath can i do to fix it?

@Buzz_Nix the correct entry should be deb http://apt.insynchq.com/mint rafaela non-free contrib.
