Update the Kernel

Keeping your kernel up to date ensures you have the latest security patches and performance improvements.

Prerequisites

Update Commands

sudo apt update
sudo apt upgrade -y

sudo yum update -y

Or on newer systems:

sudo dnf update -y

Kernel updates require a system reboot to take effect.

After the update completes, restart your server:

sudo reboot

Your VPS will be unavailable for a few minutes during the reboot. See Restart for more details.

After rebooting, check your kernel version:

uname -r

Schedule regular updates to keep your system secure. Consider setting up automatic security updates for critical patches.
