Ubuntu encourage upgrading between releases by running a command, instead of by manually editing sources and getting on with it. This tool's name is do-release-upgrade, and I believe it should just be doing:

sed -i 's/wily/xenial/g' /etc/apt/sources.list /etc/apt/sources.list.d/*

This command does not explain what it wants to do, or why it is doing anything. It has, in the past:

• Disabled repos I was using, and hence broken the software in them.

    Note that due to returning the created figure object, when this funciton is called in a
    notebook the figure willl be printed twice. To prevent this, either append ; to your
    function call, or modify the function by commenting out the return expression.
