• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be 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.

    Plesk Update: Can't connect to backend: No such file or directory

    After the update from 12.5 to 17 we have the same issue. Both solutions (plesk installer --select-release-current --reinstall-patch --upgrade-installed-components) and (https://kb.plesk.com/en/122949) did not solve the problem. Can we try something else?
