Kodi updates

Hi folks I have kodi working on a volumio raspberry pi installation.
It is working though slow to start, anyway I was wondering if there is a way to update kodi 17 to the lastest version 18? If so how? Thanks
meanwhile keep social distancing.

I am curious how to do it, thats all. Kodi can take 5 minutes to boot up after volumio, and it is an older install.
