Looks like on this instance there are a few additional apt package repositories configured, which are failing. As far as I can tell, this doesn't look like Cloudron related. Can you verify that this works without issues to install latest updates:

sudo apt-get update
sudo apt-get upgrade

I wonder why it's trying to install from jessie-backports ? Is this a fresh ubuntu install or did you try to install something else prior to Cloudron?
