Server operating system version

Debian 10.13

Plesk version and microupdate number

18.0.70

Hello
I have two servers with DEBIAN OS 10.13 using Obsidian 18.0.70 update 4 received on 2 August 2025. Today the two servers send me a notification by mail and I can see a fail for updating to 18.0.71.
The error is :

It states right there

That package has been moved to archive.debian.org so you need to update your repos for anything that uses security.debian.org to archive.debian.org. Although if you ask me I think you should either upgrade your distros to version 11 or deploy a new Debian 12 and migrate the sites over but that's just my 2 cents lol. (Plesk has a guide for distro upgrades over at https://support.plesk.com/hc/en-us/...-upgrade-procedure-on-Linux-server-with-Plesk if you want to try to upgrade it, just be sure to take a snapshot of the servers or have a backup available IF you go that route).
