Turnkey Drupal 6 -- NO_PUBKEY AED4B06F473041FA

I find today that apt-get update no longer updates my Turnkey Drupal 6 VM: I'm now getting a NO_PUBKEY AED4B06F473041FA

Is this something I've done or perhaps a known issue?

Maybe related to Debian changing their signing key

I think this may have something to do with the previous stable version of TurnKey Drupal 6 being pinned to Debian stable for security updates. Debian updated their archive key recently on Feb 9th, 2011.

OK, that looks like the reason...

Thanks, that looks like the reason. I'm still rather stuck though. Does anyone have a solution? I've tried adding debian-archive-keyring (failed) and then ubuntu-keyring (install success but apt-get update still fails).

Does anyone else have this issue with Turnkey Drupal 6?

What about upgrading to the latest stable?

Personally I'd suggest you use TKLBAM to migrate your data to the latest (v11.1) version.

apt -get update

Thanks from Thailand.
my command is
# pgp --recv-keys AED4B06F473041FA
# pgp --armor --export AED4B06F473041FA | apt-key add -
# apt -get update

I can confirm that this works

I ran into this issue on an older VM and can confirm that the above solution does in fact work, except for a typo in the command name which is gpg not pgp:
gpg --recv-key AED4B06F473041FA
gpg -a --export AED4B06F473041FA | apt-key add -

Thanks, Liraz.

Yes, that was it I think!

Yes, thanks Liraz -- I don't remember exactly what fixed it but there was some messing around required with the new key.

Alternate Fix

As root:

apt-key adv --keyserver pgp.mit.edu --recv-key AED4B06F473041FA

Has the same effect as the proposal, with one less level of indirection.

gpg Key Update

Thankyou so much! It helped with one Ubuntu / Debian Hybrid Box :)
