Newbie Ubuntu user here. Currently I have the 16.04LTS (I don't know if mine is 16.04.1 but I downloaded and installed this version of mine the day 16.04LTS officialy released last April 2016). Should I upgrade to 16.04.2? If so, how? I mean, do I have to download the 16.04.2 installer or is there a update command?

You can run the Sofware Updater any time you want, including setting it to run automatically.

No need. Just keep installing the regular updates to your OS.

These minor releases are just new installer images so that new users don't immediately have to download a huge chunk of data.

Your Ubuntu will be automatically updated to 16.04.2 when the next package update kicks in. You probably had some updates around Tuesday which upgraded you to status "16.04.2" (run "lsb_release -a" in a terminal to verify). Yesterday it was only the ISO images that were released.

The important issue with 16.04.2 is that you can now decide easily upgrade the Linux kernel from the original 4.4 version, to the new 4.8 version. This 4.8 Linux kernel version was released in Ubuntu 16.10 (Oct 2016) and it has been promoted to the new kernel for 16.04.2.

May sound complex :-). There is a nice graphic in https://wiki.ubuntu.com/Kernel/LTSEnablementStack that explains it well.

If you can ssh into your machine, it will tell you in the initial welcome message. I've been running it on my server since soon after release (I've only ever updated), and I've just now logged into it:

Welcome to Ubuntu 16.04.2 LTS (GNU/Linux 4.4.0-62-generic x86_64)

sudo apt update and sudo apt upgrade will do it for you. To check what version you are on simple do cat /etc/os-release

Or, for a more cross-distro approach, `lsb_release -a`, although it requires the `lsb-release` package installed.

Truly cross distro is cat /etc/* release
