• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Can't update to Plesk 9.0

Despite updating my key the installer just keeps bombing out:

Exchanging information with licensing server.base
Downloading the file PSA_9.0.0/plesk_getkeyinfo.sh: Failed to check whether a new license key is available.
ERROR: Failed to check whether a new license key is available.
