dget complains that public key not found

Hi,

Not sure if it's a proper place to ask. I'm trying to backport jessie's rfc5766-turn-server package to wheezy. I'm following the steps specified on this page: https://wiki.debian.org/SimpleBackportCreation But when I'm trying to download .dsc file, dget says:

$ dget -x http://ftp.de.debian.org/debian/pool/main/r/rfc5766-turn-server/rfc5766-turn-server_2.6.5.2-1.dsc

dget: retrieving http://ftp.de.debian.org/debian/pool/main/r/rfc5766-turn-server/rfc5766-turn-server_2.6.5.2-1.dsc

rfc5766-turn-server_2.6.5.2-1.dsc:

dscverify: rfc5766-turn-server_2.6.5.2-1.dsc failed signature check:

Validation FAILED!!

What am I doing wrong? Should I ignore this error? Or does this mean there's some issues with my server? I updated debian-keyring package, to no effect. My hosting provider is hetzner and I'm using his mirrors, but I confirmed debian-keyring package doesn't differ from what is in other mirrors. Just in case, this is the question I was asking when I tried to backport openssl package: http://serverfault.com/questions/587486/dget-complains-that-public-key-not-found Thanks in advance for your replies.
