Ubuntu 16.04.1 Released: Do I have to upgrade my system and if so how? [duplicate]

Solution 1:

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.

Solution 2:

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.
