sudo rm /etc/apt/sources.list.d/xenial-partner.*

Will help clean up. Also use software centre and disable the CD as a source of packages, or comment the top few lines out in /etc/apt/sources.list

You should also search the file and change the word "lucid" to "xenial".

You also need to install the getdeb key.

Did you by any chance copy your sources.list between 2 installs of Ubuntu? It looks that way
