Frequently asked questions
Is Debian 9 still safe to use?
Debian 9 left standard support on 1 Jul 2022. It still receives security updates under extended support until 30 Jun 2027 — 268 days from now — but only if you are enrolled. Without it, no fixes reach you.
Can I still download Debian 9?
Yes — the final release (9.13) 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 9 to?
Upgrade to Debian 13, the newest actively supported branch (supported until 30 Jun 2030).
