when I update using 'apt-get update' on ubuntu-14.04, I got the following error,

W: GPG error: http://packages.osrfoundation.org trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 67170598AF249743

I've tried following command given in some forum

apt-key adv --keyserver keyserver.ubuntu.com --recv-key 67170598AF249743

the output is as follows

Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.XI2D9gTkMc --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --keyserver-options http-proxy=http://202.141.80.80:3128 --recv-key 67170598AF249743
gpg: requesting key AF249743 from hkp server keyserver.ubuntu.com
gpgkeys: key 67170598AF249743 not found on keyserver
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

and I've tried

 gpg --keyserver keyserver.ubuntu.com --recv-key 67170598AF249743

the output is

gpg: requesting key AF249743 from hkp server keyserver.ubuntu.com
gpgkeys: key 67170598AF249743 not found on keyserver
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

with command gpg -a --export 67170598AF249743 | sudo apt-key add -, I got the following result

gpg: WARNING: nothing exported
gpg: no valid OpenPGP data found.

and still I get the GPG error same as above, can anyone suggest me a solution?

  • Are you running these commands under sudo privilege ? ie sudo gpg --keyserver keyserver.ubuntu.com --recv-key 67170598AF249743 ?

  • by the way do you really need OSRF Repository ? I mean packages.osrfoundation.org ? As a work around you can exclude it and run update.. here is how .. askubuntu.com/questions/43345/how-to-remove-a-repository

  • I've added the repos of gazebo myself, will the GPG keys be available in keyserver.ubuntu.com for those repos added by user?

    you should have mentioned this at the start of your question, just like your other question... askubuntu.com/questions/611209/gpg-error-http-repos-rcn-ee-net

seems keyserver.ubuntu.com is missing gpg keys for packages.osrfoundation.org

Download gazebo.key from below using wget.. 

wget  http://packages.osrfoundation.org/gazebo.key

and import it 

sudo apt-key add gazebo.key

Then try 

sudo apt-get update && sudo apt-get upgrade
