No public key
"Backports is now an official service residing at backports.debian.org. Previously, when the service was hosted at backports.org, users were required to install the debian-backports-keyring package in order to verify the integrity of downloaded backports before installation. This is no longer necessary. However, APT may warn with the following message after updating package lists: 'W: There is no public key available for the following key IDs: EA8E8B2116BA136C' This is due to Debian Backports release files currently being double-signed (official ftpmaster key and old backports.org key). The warning is an APT bug and can be safely ignored.
I just did a fresh install of Debian stable and this warning did not occur when using Backports. Does that mean the bug has been fixed and the section can be deleted? --openrebel
Which backport to use?
This is my understanding, not sure whether or not it is correct, but here goes:
"If you are running lenny (current stable release), then you need to use lenny-backports repository for backports."
It wasn't clear to me if you should look for squeeze-backports ....
