How to upgrade Kali packages

A quick way to make sure your packages are up to date is to run this command:

apt-get update && apt-get upgrade

It runs apt-get update first, which checks for updated version. Then it runs apt-get upgrade which handles the installation. Depending on your system, this could take a minute or ten minutes. Running this command on a fresh installation of Kali usually takes about 10-15 minutes to complete.
