Ubuntu Trusty GPG error: NO_PUBKEY

While doing some routine “sudo apt-get update”, I ran across a few errors like such

W: GPG error: http://ppa.launchpad.net trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A6804EA8EAE0D85C

and much I tried was not working. Luckily I came across a very helpful blog and the approach that worked for him, also worked for me. His approach is to basically manually download the problem Key and add it.

1. Go Here

2. Search String: 0xWhateverKey (ie. my f’d pubkey was A6804EA8EAE0D85C, so I searched “0xA6804EA8EAE0D85C” )

3. Click pub link

4. Copy the entire Public Key Block

example:

-----BEGIN PGP PUBLIC KEY BLOCK-----

-----END PGP PUBLIC KEY BLOCK-----

5.  Paste into blank file “key1” & save in home folder or anywhere

6. cd into that folder, run command “sudo apt-key add key1″ , it’ll respond “OK”

7. then just “sudo apt-get update” and sigh with relief!
