Avoiding prompts

To avoid any prompts from Debian packages like Grub or mySQL, you can temporarily set an environment variable. This ideal for provisioning scripts in Containers like Vagrant/Docker.

export DEBIAN_FRONTEND="noninteractive"

Also make sure to auto confirm apt with the -y parameter

apt -y upgrade
