Security updates

The software on your server gets regular security fixes. When they aren’t installed, known weak spots stay open — and attackers scan the internet for exactly those. Keeping up with updates is one of the simplest ways to stay safe.

How to fix it by hand

    Downloads the latest information about available updates.

    sudo apt update

    See what’s waiting

    apt list --upgradable
  3. 03

    Install the updates

    Installs available updates. Do it at a quiet time for your site.

    ls /var/run/reboot-required

FAQ

Security updates: common questions

Will installing updates break my website?

Security updates are designed to be safe, and problems are rare. Installing them one at a time and checking the site after each keeps the risk low.

How often should I install security updates?

As soon as practical — ideally every week. Attackers often start using a known weakness within days of it being published.
