There's probably an easier way, but you can import the key from a
keyserver using gpg:

  gpg --recv-key 0xA70DAF536070D3A1

Then import to apt using apt-key;

  gpg --export -a 0xA70DAF536070D3A1 | apt-key add -

It's also possible that the mirror you were downloading from was merely
out of sync temporarily.

That big nasty screenful of apt-fail points to the post-removal scripts
for gnome-screensaver and libgnomevfs2-common crashing.  Try dpkg -a
--configure; if it still fails, I've been know to trash the files
under /var/lib/dpkg/info/culprit.post-rm (or whatever) to force dpkg
into continuing in this sort of situation.  Or even
editing /var/lib/dpkg/status - the format is straightforward enough ;-)

Good luck,
Sam.
