Updating Ubuntu packages, apply Ubuntu patches manually using the command line

Updating your Ubuntu system for the latest updates or patches manually is a 2 step activity, from the command line. Start up the terminal on your system, then enter the commands in italics as shown below.
$ sudo apt-get update <enter>
$ sudo apt-get upgrade <enter>

If you are not comfortable doing the above at the command line, you can use the Update Manager to apply patches and keep your Ubuntu system up to date.
