I think I figured this out, it was apparently caused by 'apt-listchanges' and/or 'apt-listdifferences'.

I would go with the listdifferences as the listchanges have never caused a single problem for me in the many many years I have used it, never heard of the listdifferences until this thread.

I uninstalled these two packages and the problem seems to have disappeared, I have no idea what or who installed them to begin with (whether it was me or whether they got installed as a 'suggestion' from some other package).

Though I fail to see why you need the src packages to update your install as that is what it fails on.

Even enabling the deb-src here does not produce the same error you are getting.

What do I have to do to avoid these warning in future updates, am I missing some "trusted keys" package?
