Fix GPG Key Errors For Bad Keys

Today I tried to update my ubuntu 10.10 but unfortunately, I found the error regarding the GPG keys saying the signature could not be verified. A simple solution for this is presented in this post.

The error I got was as below:

W: GPG error: http://ppa.launchpad.net maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A9A06AEF9CB8DB0

My solution was to update the keys using the same hex number shown in the error.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5A9A06AEF9CB8DB0

This simply worked as a charm. I hope this works for you as well. :)
