[repository] How to trust a apt repository : Debian apt-get update error public key is not available: NO_PUBKEY <id>

Trying to update some repositories on Debian Etch installation and getting the following errors from running "apt-get update"

W: GPG error: http://www.debian-multimedia.org etch Release: The following signatures couldn't be verified because teh public key is not available: NO_PUBKEY 07DC563D1F41B907
W: You may want to run apt-get update to correct these problems

The irony of it instructing me to run apt-get update is a nice kicker...

This question is related to repository debian upgrade gnupg apt

The answer is


I had the same problem of "gpg: keyserver timed out" with a couple of different servers. Finally, it turned out that I didn't need to do that manually at all. On a Debian system, the simple solution which fixed it was just (as root or precede with sudo):

aptitude install debian-archive-keyring

In case it is some other keyring you need, check out

apt-cache search keyring | grep debian

My squeeze system shows all these:

debian-archive-keyring       - GnuPG archive keys of the Debian archive
debian-edu-archive-keyring   - GnuPG archive keys of the Debian Edu archive
debian-keyring               - GnuPG keys of Debian Developers
debian-ports-archive-keyring - GnuPG archive keys of the debian-ports archive
emdebian-archive-keyring     - GnuPG archive keys for the emdebian repository
