There are many questions with answers on Ask Ubuntu about upgrading, for example, from 14.04 to 16.04. (Between LTS versions.) I recently heard that 16.04.1 has been released.

Do I have to do anything more than sudo apt-get update && sudo apt-get upgrade to update my system to 16.04.1?

A simple question which requires little explanation! Hopefully also a simple answer?

Note: I have 16.04 currently!

Note: The linked question does not explain how to upgrade from 16.04 to 16.04.1. (For example.) However it does cover upgrading from 14.04 to 16.04. (For example.) Is the method the same? (The answer posted below and in the comments suggests no.)

To upgrade from 16.04 to 16.04.1:

sudo apt update && sudo apt upgrade

To upgrade from 14.04.x to 16.04.1:

Step 1: Back up your current system. "Dirty" upgrades from one release to another don't always go as planned, so you should make sure that you've backed up any data you don't want to lose.

Step 2: Update your current system with sudo apt update && sudo apt full-upgrade.

Step 3: Make sure you have the update-manager-core package installed: sudo apt install update-manager-core

Step 4: Upgrade to the current release: sudo do-release-upgrade

All that being said, I would recommend a "clean" install of 16.04.1 instead, especially since the transition from 14.04 to 16.04 involves going from SysVInit to systemd.

One part of your question wasn't addressed: "Do I have to upgrade my system?"

No, you do not. 14.04 will be supported until April 2019.

There are many reasons to upgrade, but you do not have to.
