Frequently asked questions
Is Debian 11 still safe to use?
Debian 11 left standard support on 31 Aug 2026. It still receives security updates under extended support until 30 Jun 2031 — 1,729 days from now — but only if you are enrolled. Without it, no fixes reach you.
Can I still download Debian 11?
Yes — the final release (11.11) generally remains available from vendor archives and OS package mirrors, but installing it means running software with known, unpatched vulnerabilities.
What should I upgrade Debian 11 to?
Upgrade to Debian 13, the newest actively supported branch (supported until 30 Jun 2030).
