Plesk Obsidian 18.0.70

Hello,

I have Plesk on an Ubuntu 20.04 LTS machine.

I wanted to know if I can upgrade to Plesk Obsidian 18.0.71 Update 1.

I'm noticing that the update is no longer automatic. I'm getting this error:

Motivo: 2025-07-20 06:26:13 INFO: pum is called with arguments: ['--list', '--repo-info', '--json']

Thank you for support
