How do I upgrade from 14.04 to 14.04.2?

Question

I want to upgrade from 14.04 to 14.04.2 without doing a fresh install.

I want to keep all my configuration the same.

How can I do that?

Answer 1

Just install all the updates and you'll get it.

The "point releases" of Ubuntu LTS versions aren't something special, as standard releases are. The same repositories are used.

In other words, 14.04.2 = 14.04 + all current updates.

Answer 2

If you want to use the new 3.16 kernel coming with the hardware enablement stack, you should use these terminal commands:

sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

Answer 3

I'm using 14.04.1 and when I used Software Updater it said that no updates were available. But when I did the terminal commands

sudo apt-get update
sudo apt-get upgrade

it fetched and installed ~ 2 M of updates, and now I'm at 14.04.2

My Lubuntu 14.04.1 installation did exactly the same thing.
