Question
Does Plesk support Debian 11 (Bullseye)?
Answer
Not anymore. Debian 11 was supported from Plesk Obsidian 18.0.42 to Plesk Obsidian 18.0.81.
Support for Debian 11 was dropped in Plesk Obsidian 18.0.81. Starting with Plesk Obsidian 18.0.82, Debian 11 is removed from the list of supported operating systems, and new Plesk Obsidian releases are no longer published for it. Debian 11 has reached its end of life (vendor EOL date: August 31, 2026).
The latest Plesk version available for Debian 11 is 18.0.81.
To keep receiving new Plesk releases, do one of the following:
- Dist-upgrade the server to Debian 12 using the dist-upgrade tool
- Migrate the hosted domains to a Plesk server running a supported OS: Plesk Migration and Transfer Guide
Comments
When will ModSecurity Atomic ruleset be available on Debian 11? What about Watchdog? And what about Debian 12?
