I got a error while I was running the apt-get update command the error was "GPG error: http://download.virtualbox.org lucid Release: The following signatures were invalid: BADSIG 54422A4B98AB5139 Oracle Corporation (VirtualBox archive signing key) <info@virtualbox.org>". So I googled it and found the below steps which clears the error and it was little difficult to find so tought to blog it here.
- $ cd /var/lib/apt/lists
- $ sudo rm *virtualbox*
- $ cd partial
- $ sudo rm *
- $ sudo apt-get update
After following these steps the problem was gone. Credit goes to a user by name Frank.
