Automatic security updates

Installs security updates automatically every day.

Runs on

  • Debian / Ubuntu: supported
  • RHEL / Fedora: supported
  • Alpine: not available — Alpine has no automatic update service. Run apk upgrade regularly instead.

What it changes on your server

  • Debian and Ubuntu: installs unattended-upgrades and turns on its daily run (security updates only, the package default).
  • RHEL and Fedora: installs dnf-automatic, set to apply security updates only, and enables its daily timer.
  • Services may restart after updates; the server itself isn't rebooted.

What Shellbay asks you

Nothing. This workflow needs no details from you.

Steps

  1. Refresh the package list
  2. Install the updater
  3. Turn on daily security updates
  4. Check it's scheduled

Shellbay checks the server before the first step, and stops at the first step that fails.

When it's done

  • Security updates now install automatically every day.
