Is there anything to learn from this experience that can help us in
future? Controls are never perfect, and there's always a cost-benefit
to be done on them. No sense spending an extra 5 hours in work to
prevent a problem that occasionally causes 5 minutes in inconvenience,
for example. But, again, this isn't that situation. I have an
unbootable system which could stay that way for days.
But we don't have to give up because we cannot prevent every corner
case. Making sure that all the KF libraries are at the same version
doesn't seem like a corner case to me, especially after upstream said
that you cannot mix and match versions.

True. Controls only work when people follow them. That means they
generally fail against deliberate attempts to defeat them. When that
happens, you throw your hands up and say that the system is too broken
to fix. But I don't think that applies here. I understand that there
are some very smart and generally honest people who get the GPG keys
to the Debian repos.
