How do I fix the GPG error “NO_PUBKEY”?
I am using 10.04 LTS - the Lucid Lynx, I shutdown the computer while one software updates running. Then after i restart my computer and when the updates manager is running, the following error occurs.
Could not download all repository indexes
The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

I gone through the link How do I fix the GPG error “NO_PUBKEY”? and I ran the following command
sudo launchpad-getkeys Please wait... launchpad-getkeys is running an update so it can detect the missing GPG keys Trying to import all the missing keys gpg: requesting key 0F1B0520 from hkp server keyserver.ubuntu.com gpgkeys: key C927EBE00F1B0520 not found on keyserver gpg: no valid OpenPGP data found. gpg: Total number processed: 0 launchpad-getkeys has finished importing all missing GPG keys. Try running sudo apt-get update - you shouldn't see any key errors anymore
But when I run
sudo apt-get update again, it again shows that the key was not found on the keyserver. How to solve this problem?
