How can I stop unattended-upgrades from rebooting the machine?
Solution 1
Verify that in the configuration file: /etc/apt/apt.conf.d/50unattended-upgrades
you have set:
Unattended-Upgrade::Automatic-Reboot "false";
This will prevent the software to issue reboot also if needed by the upgrades.
Solution 2
To disable automatic upgrades altogether, just remove the package. Try:
sudo apt-get remove unattended-upgrades
See Ubuntu docs for more info. However, if you want to keep the package and configure its behaviour, see this question's solution How do I enable automatic updates?

I just had a look at my Amazon EC2 instance and noticed I had 20 minutes exactly of downtime. I didn't know what caused it so I logged in to SSH and tried upgrading my packages, and saw that the
unattended-upgrades
package needed upgrading. I went ahead and did this.After searching it seems like this package can automatically reboot your machine. Not sure why I didn't get to configure this as it came with the OS, but oh well.
Does anyone know how to prevent the package from automatically rebooting? Or how to stop it updating packages altogether? I can do that myself.

Anwar over 7 yearsYou first link's most voted answer suggest installing it and you're suggesting to remove it? Again, removing it beats the purpose of getting automatic unattendend upgrades altogether!

Anwar over 7 yearsYou may only extract that information out to point OP to the right direction? Since, it is confusing to see supporting link saying against (at first look at least) the answer.

Reid almost 6 yearsI believe you'd want to
apt-get purge
to kill unattended-upgrades in its entirety, not justapt-get remove

Serrano Pereira over 5 yearsDown vote, because removing
unattended-upgrades
is usually a bad idea. You will miss out on important security updates, especially considering this is a server instance, where you want these to be installed automatically. -
