How to enable Canonical Livepatch Services on official Ubuntu flavors such as Ubuntu MATE?

Solution 1:

Here we have two problems:

1. Livepatch is not available for this system
2. Gnome Online Accounts is required to enable Livepatch

To solve the problems we need to install Livepatch as Snap and to install GNOME Online Accounts as deb-package with:

snap install canonical-livepatch
sudo apt-get install gnome-online-accounts gnome-control-center --no-install-recommends

and reboot.

On next opening of Software & Updates the Livepatch will welcome us to Sign in:

but the corresponding part of GNOME Control Center will not open on MATE session.

To open it we need to pass environmental variable to GNOME Control Center:

env XDG_CURRENT_DESKTOP=GNOME gnome-control-center online-accounts

and setup Ubuntu One account from here.

Then open Software & Updates (software-properties-gtk) again, navigate to Livepatch tab and click on Sign In... button, confirm your account and use Livepatch:

Note: it is free for 3 machines, buy more from corresponding Canonical Livepatch Service.

From Marco Sulla's comment we have the following solution for Lubuntu. Here reinstallation of gnome-control-center is needed. To re-enable the LivePatch use commands below

sudo apt-get install --reinstall gnome-control-center
sudo canonical-livepatch disable && sudo canonical-livepatch enable $TOKEN
