• Operating system installed on the server has not reached its End of Life (EOL) and is listed among the Currently Supported OSes here.

Cause

A custom repository for Plesk packages is configured in the file /root/.autoinstallerrc:

SOURCE = https://autoinstall-archives.plesk.com

This repository may be either unreachable or not actual for the current OS.

Resolution

Enable default Plesk repository:

1. Connect to the Plesk server via SSH.

2. Rename the repository file:

   # mv /root/.autoinstallerrc /root/.autoinstallerrc.bak

3. Start Plesk Update.
