The public key usually is somewhere on the site where you got the name
of the repository from, "http://debian-multimedia.org etch". By the way,
usually it is not advisable to install packages for Debian in Ubuntu.

the problem is at your end, which is supported by what you wrote next:

Please post the contents of the file /etc/apt/sources.list. Something
seems wrong there.
