Apt-key gpg tip

How many times you have stumbled on a mistake like this?

W: GPG error: <repository address> jaunty Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 2A8E3034D018A4CE

NOTE: This is in away unsecure as pointed out in here : Dealing with apt’s GPG signing stuff — the right way. In the following link you can read up on how to do it the real way.

gpg --keyserver subkeys.pgp.net --recv-key fingerprint

For Debian:

gpg --export fingerprint | apt-key add -

For Ubuntu:

gpg --export fingerprint | sudo apt-key add -

But you can put this easy in a script:

For Ubuntu:

#!/bin/bash
gpg --keyserver subkeys.pgp.net --recv-key $1
gpg --export $1 | sudo apt-key add -

For Debian:

#!/bin/bash
gpg --keyserver subkeys.pgp.net --recv-key $1
gpg --export $1 | apt-key add -

You can run it as following:  fixgpg.sh 2A8E3034D018A4CE .

I placed it in /usr/bin, the script is easily called and solved, plus you don’t have to remember the code .
