	~~Check for current version~~
	~~If your machine is running older version then 16.04 which is the latest long term supported version, please follow the following commands to upgrade your machine to the latest version.~~
	*First check your current Ubuntu version by running the following command:
	~~<code>lsb_release -a</code>~~

	~~If you find that your machine is already running the following version or higher than:~~

	~~Description:Ubuntu 16.04.1 LTS~~
	~~Release:16.04~~

	~~Then there is no need to upgrade the OS~~

	~~==== Upgrade ====~~

	*First become super user "root":
	~~<code>sudo -i</code>~~

	*Begin by updating the package list:
	~~<code>apt-get update</code>~~

	*Upgrade installed packages to their latest available versions:
	~~<code>apt-get upgrade</code>~~

	*Once upgrade finishes, use the dist-upgrade command, which will perform upgrades involving changing dependencies
	~~<code>apt-get dist-upgrade</code>~~

	*Now that you have an up-to-date installation of Ubuntu 16.04 LTS, you can use <code> do-release-upgrade</code> to upgrade to the Ubuntu 16.04 LTS release.
