When I tried to clean up my computer, somehow I erased a needed library for running K3B, and also got an error

W: GPG error: http://ppa.launchpad.net hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7781BA0134BEEE14

W: You may want to run apt-get update to correct these problems

SOLUTION

In order to intall the missing package, just reinstall the program

sudo apt-get update

sudo apt-get install k3b

This should fix the first problem. The second one is a little more tricky, but thanks to blackgr (user of ubuntuforums), we have a little script (below), which makes our lives easier. Download, unzip and run it in the konsole

cd Desktop

unzip launchpad-update.zip

sudo ./launchpad-update

sudo apt-get update

The last line is just to check the problem was solved.

Enjoy!
