GPG key error updating aptitude, Debian upgrade

I had an old Debian Etch machine which I did not upgrade for some time, and when I attempted to install ghostscript by using Synaptic, I've got some unmet dependencies errors with libc6 and libc6-dev. Any attempt to reinstall or upgrade these packages failed, so I decided to try to upgrade the whole system to Lenny:

• I replaced etch with lenny in /etc/apt/sources.list
• #sudo aptitude update
  But I've got this error:

  "There is no public key available for the following key IDs: xxxxxxxxxxxxxxxx"

  The error can be solved downloading the GPG signatures with these commands:
  #gpg --keyserver keyserver.ubuntu.com --recv xxxxxxxxxxxxxxxx
#gpg --export --armor xxxxxxxxxxxxxxxx | apt-key add -

  I've tried a few servers (subkeys.pgp.net, keyserver.pgp.com, wwwkeys.eu.pgp.net) but they could not find the "right" keys...
  Then I did the #sudo aptitude update again.
• #sudo aptitude install apt dpkg aptitude
• #sudo aptitude full-upgrade

And then I've been able to install ghostscript.
