Last year I got a raspberry pi 2 with (OSMC ) Kodi already installed on it. I want to upgrade the kodi version as simply as possible. Any help ?
I can see a couple of options on the osmc.tv/wiki page:
By default, OSMC will check for updates automatically and prompt you. You can refine this via My OSMC. If you are using the default OSMC skin, then My OSMC will be accessible via your Home screen. If you are using Confluence then it will be available via the Settings sub-menu. For other skins, My OSMC can be found via the Programs section.
To change the update schedule, select Updater. You will now be able to configure OSMC's update behaviour.
Did you know?: you can also force an update check on demand by going to My OSMC -> Updater -> Manual Controls -> Check for updates now.
We recommend users use the OSMC Updater via Kodi, but running:
sudo apt-get update sudo apt-get dist-upgrade
will keep your system up to date and will not cause any issues.

I hope this helps
