    sudo dpkg -i /home/osmc/kernel.deb
    rm /home/osmc/kernel.deb

Edit the file /etc/apt/sources.list
Add the following line: deb http://apt.osmc.tv stretch-devel main
Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot

Should I favour one or the other?
