• 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.

Resolved Failed to update the extension (Debian 8 VPS)

TimReeves

Regular Pleskian
I run Plesk on about 7 servers, all Debian 8 or 9, all without Bind installed (the Domains are all managed at domain specialist companies). All Updating is going fine everywhere, except at one server I am now seeing the warning popup (bottom right) when logged in to Plesk:

Failed to update the extension
Execution of /opt/psa/tmp/moduleQIxvB5/plib/scripts/pre-install.php failed with exit code 1 and the output:
DNS Service is not installed on this instance.

I know that there are various known problems, e.g. with the Lets Encrypt Extension, when Bind is not installed. But with this message, I don't know where to start. Can anyone give me a tip?

Thanks, Tim
