Question

Is Ubuntu 26.04 supported by Plesk?

Answer

Ubuntu 26.04 is supported starting with the Plesk Obsidian 18.0.81 release.

Known limitations:

PHP 7.3 and older versions are not shipped because these handlers have reached their end of life.

Note: Unsupported PHP handlers can still be manually installed and added to Plesk.
Mailman is currently not available, due to the bug on vendor side.
MySQL 5.7 is not supported.
.NET packages are not yet present in Microsoft repositories, so .NET Toolkit extension currently has only dotnet8 package, which is available in OS repositories.
SOGo Webmail is supported, but only in nightly packages, which may affect the stability of SOGo Webmail.

Does Plesk Obsidian 18.0.81 with Ubuntu 26.04 still support PHP version 7.4?
Also, which version of MariaDB is installed by default?
