How do I fix the GPG error “NO_PUBKEY”?
I am using 10.04 LTS - Lucid Lynx.
I shutdown the computer while a software update was running. Then after I restarted my computer and while the update manager was running, I got this error:
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.
GPG error: http://toolbelt.herokuapp.com ./ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C927EBE00F1B0520 Failed to fetch http://ppa.launchpad.net/rabbitvcs/ppa/ubuntu/dists/**DISTRIBUTION**/main/binary-i386/Packages.gz 404 Not Found
I went through the answers to How do I fix the GPG error "NO_PUBKEY"?
and I tried this
$ 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?
