GPG Keys Missing, Can't Be Found on Keyserver Either

Question

So this error has been popping up a lot so I thought I'd resolve it:

W: GPG error: http://cfengine.com precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 535C743689107B44

So I did some research and tried these solutions

gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv 535C743689107B44

and

sudo apt-key adv --keyserver.ubuntu.com --recv-keys 535C743689107B44

both of which terminated with this message

gpgkeys: key 535C743689107B44 not found on keyserver
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

Any insights are appreciated

Answer 1

You missed the first step in the documentation...

http://cfengine.com/cfengine-linux-distros

To install CFEngine using these repositories, follow these steps: For Debian-based systems (apt):

Download and install the CFEngine GPG key:


# wget http://cfengine.com/pub/gpg.key
# apt-key add gpg.key
# rm gpg.key

Actually I could "fix the issue" for you :) CFengine key is now uploaded to pgp.mit.edu, so if you use that as a keyserver, it should work.
