- 28. Nov 2010 - Apparently in some odd cases Ubuntu doesn't automatically get all needed GPG public keys during the system upgrade. I just came across with this issue after upgrading one 64bit HP laptop from Ubuntu 10.04 to 10.10. (not a clean install, but upgrade thru Update Manager) After the upgrade Synaptic update stopped working with the following error about missing public key: GPG error: http://extras.ubuntu.com
maverick Release: The following signatures couldn't be verified because
the public key is not available: NO_PUBKEY 16126D3AXXXXXXXX"
Not to panic! The fix for the problem is quick and easy! One just has to add that missing key with the below command: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys XXXXXXXX Just pick the last eight digits from the error message to the end of the fix command.More on this can be found from: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/656614 |
