Before i start, i've tried the solution from this thread

How do I remove a malformed line from my sources.list?

but unfortunately, the steps performed in that thread are already covered for me.
The error I'm getting is:

Malformed line 3 in source list /etc/apt/sources.list.d/cloudarchive-havana.list (dist)

E: The list of sources could not be read.

I'm not too sure what is causing this but it won't allow me to use the ubuntu software center or perform any updates.

Here is the output from the malformed directory:

deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/havana main



deb-src http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/havana main



deb http://docs.openstack.org/havana/install-guide/install/apt/content/basics-packages.html

Can anyone point me in the direction of a solution please?
