release upgrade should deactivate /etc/apt/preferences*

Bug Description

The Ubuntu release upgrader should deactivate any apt-pinning definded in /etc/apt/preferences or /etc/apt/preferences.d/* and notify the user when doing so. A similar behaviour is already the case when external (PPA) sources are deactivated.

Otherwise, some random irritating error will be shown which does not show the origin of the problem. In my case: "kubuntu-netbook cannot be installed".

I use apt-pinning a lot and I know what I am doing. But when upgrading, I usually forget that I have pinned packages or sources and it takes me some time to find out what's wrong. It would just be nice to warn the user and/or deactivate the pinning in /etc/apt/preferences/*

The answer I got is that this may be a bug, ubuntu-release-upgrader should deactivate your apt-pinning. Can you see if the logs of the upgrade are still in /var/log/dist-upgrade and upload all the files there to this bug report?

I don't believe logs would add any additional information so I am setting the bug to Triaged.
