Keeping your Linode instances up to date is crucial for maintaining security, stability, and performance. Automatic updates can simplify the management of your cloud infrastructure by ensuring that patches and improvements are applied without manual intervention. In this article, we will walk you through the steps to enable automatic updates on your Linode instances, along with key considerations.

Why Enable Automatic Updates for Linode Instances?

By enabling automatic updates, you ensure that your Linode instance remains secure and free of vulnerabilities. Unpatched systems are often exposed to cyber threats, which can be mitigated by ensuring timely updates. For businesses using Linode Cloud Support Services, automating these updates can reduce manual workload and ensure continuous, safe operations.

Steps to Enable Automatic Updates

1. Install Unattended-Upgrades: The unattended-upgrades package is available for most Linux distributions and helps apply updates automatically.

For Debian/Ubuntu, use:

sudo apt install unattended-upgrades

For CentOS/RHEL, use:

sudo yum install yum-cron

2. Configure the Automatic Updates:

• For Ubuntu/Debian systems, configure the /etc/apt/apt.conf.d/50unattended-upgrades file to define which types of updates (security, all packages, etc.) should be installed automatically.
• For CentOS, configure /etc/yum/yum-cron.conf to customize which updates are applied and when.

3. Testing the Configuration: After configuring, you can simulate an update process to verify everything works as expected:

sudo unattended-upgrades --dry-run

4. Monitor Logs: You can monitor the logs to confirm updates are happening as scheduled. Logs for automatic updates are usually stored in /var/log/unattended-upgrades/ or /var/log/yum.log.

Using Linode Cloud Support Services, you can request help from Linode’s experts to ensure that your instances are set up correctly, keeping your infrastructure secure and up-to-date.
