How to Configure Automated Security Updates on Debian 11
Debian 11, often known as “Bullseye,” is a widely used Linux system that is renowned for its reliability and security. Configuring automated security updates is one technique to increase the security of your Debian 11 system. In this post, we will demonstrate how to configure Debian 11 for automatic security updates.
Step 1: Install the unattended-upgrades package
Installing the unattended-upgrades package, which provides the essential tools to automate the security update process, is the initial step. Open a terminal and enter the command below:
sudo apt install unattended-upgrades
Step 2: Configure the unattended-upgrades package
You must setup the unattended-upgrades package to enable automatic security updates after installing it. Open the configuration file using the text editor of your choice:
sudo nano /etc/apt/apt.conf.d/50unattended-upgrades
Uncomment the following lines to enable automated updates for security:
// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
"${distro_id}:${distro_codename}-security";
// "${distro_id}:${distro_codename}-updates";
// "${distro_id}:${distro_codename}-proposed-updates";
};
You can also tailor the setup to your specific requirements. For instance, you can configure the email address to get updates installation notifications:
Unattended-Upgrade::Mail "[email protected]";
Save and close the file when you’re done.
Step 3: Enable automatic security updates
Now that the unattended-upgrades package has been configured, you must enable it to receive automatic security updates. Open the configuration file using the text editor of your choice:
sudo nano /etc/apt/apt.conf.d/20auto-upgrades
Remove the following statement to activate automatic security updates:
APT::Periodic::Update-Package-Lists "1";
Save and close the file when you’re done.
Step 4: Test the automatic security updates
With the following command, you can simulate a security update in order to verify that the automatic security updates are functioning properly.
sudo unattended-upgrades --dry-run --debug
This command lists the packages that would be upgraded if a security patch were available. After a security update is installed, you should receive a message if everything is operating normally.
