How do I fix the GPG error “NO_PUBKEY”?
I am new to Ubuntu and am having troubles Updating. Here is the error I'm receiving:
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 5A9BF3BB4E5E17B5 W:Failed to fetch http://ppa.launchpad.net/ailurus/ppa/ubuntu/dists/oneiric/main/source/Sources 404 Not Found W:Failed to fetch ...
Can someone please help me figure out what my problem is and how I might correct it?
