In my /etc/apt/apt.conf.d/50unattended-upgrades i found this:
// Automatically reboot *WITHOUT CONFIRMATION*
// if the file /var/run/reboot-required is found after the upgrade
//Unattended-Upgrade::Automatic-Reboot "false";
The issue is that I don't know what the default value is and so if I need to uncomment the line (I don't want my server to reboot btw).
Should I uncomment the line by safety? Are there further actions to perform after doing that?
