Ubuntu and Debian Security in Short

Ubuntu and Debian fix security flaws in their own packages, usually by adding the fix to the version they shipped rather than moving to a new version. So apt keeps you safe as long as two things are true: updates are being installed, and your release is still supported.

How to Keep Ubuntu and Debian Patched

  • Turn on unattended-upgrades for security updates. Check /var/log/unattended-upgrades/ now and then to see it's working.
  • Reboot after kernel updates (/var/run/reboot-required appears when one is needed) and restart services after library updates (needrestart).
  • Know when your release stops getting updates. Ubuntu LTS releases get five years of standard support; Debian releases get about three years, then two more of LTS. See Bobble Solutions' end-of-life tracker for dates.
