+> **Deprecation notice**: Support for running Kong Gateway on
+Debian 8 ("Jessie") is now deprecated, as [Debian 8 ("Jessie") has reached End of Life (EOL)](https://www.debian.org/News/2020/20200709).
+Starting with Kong Gateway 3.0.0.0, Kong is neither building new Debian 8 ("Jessie") images nor packages. Nor will Kong test package installation on Debian 8 ("Jessie").
+> If you need to install Kong Gateway on Debian 8 ("Jessie"), see the documentation for
+[previous versions](/gateway/2.8.x/install-and-run/debian/).
+> <br><br>
+> Kong Gateway Enterprise subscriptions can still use Debian 8 ("Jessie") in 2.8, but support
+for Debian 8 ("Jessie") is planned to be removed in 3.0.
