apt-get/aptitude: "public key is not available"

[Wolfgang Pfeiffer <roto@gmx.net>]

Hi All


dpkg -l aptitude apt
             
          [ ... ]
+++-==============-==============-============================================
ii  apt            0.6.41         Advanced front-end for dpkg
ii  aptitude       0.2.15.9-6.0.2 terminal-based apt frontend

With the latest aptitude/apt-get doing an 'apt-get update' or
'aptitude update' I get an error for one entry (excerpt from
/etc/apt/sources.list)

deb http://honk.physik.uni-konstanz.de/~agx/linux-ppc/debian/ mplayer/
deb-src http://honk.physik.uni-konstanz.de/~agx/linux-ppc/debian/ mplayer/

Here's the error message for 'apt-get update':

Fetched 482B in 2s (197B/s) Reading package lists... Done W: GPG
error: http://honk.physik.uni-konstanz.de mplayer/ Release: The
following signatures couldn't be verified because the public key is
not available: NO_PUBKEY BDCE3370C88CEDF6 W: You may want to run
apt-get update to correct these problems


Then this:

# gpg --keyserver hkp://subkeys.pgp.net --recv-key BDCE3370C88CEDF6
gpg: requesting key C88CEDF6 from hkp server subkeys.pgp.net
gpgkeys: key BDCE3370C88CEDF6 not found on keyserver
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0


Anyone?

Thanks in anticipation
Wolfgang
