Not to contradict you, since my understanding of these issues is
strongly limited, but apt seems to think that it cannot validate the
archive?

Running: su -c "apt-get upgrade"
[...]
The following packages will be upgraded:
  liboil0.3 libsensors3 libssl-dev libssl0.9.8 lm-sensors manpages manpages-dev openssl unzip
[...]
WARNING: The following packages cannot be authenticated!
  libssl-dev openssl libssl0.9.8 manpages manpages-dev liboil0.3 libsensors3 unzip lm-sensors

If understand that the whole release is what is signed, and that then
the urls in the release are therefore trusted (I assume with md5
checksum), then it seems APT does not beleive the release is signed with
the 2005 key, or does not know how to 'fall back' to the 2005 key.
