New to Proxmox and testing it for the first time. After performing a fresh install using the 8.3.1 ISO, everything seemed to work fine, until I rebooted for an upgrade. I added the Proxmox non-subscription repo and ran a dist-upgrade. Following the upgrade, I found that some users had resolved the issue by doing a fresh install of version 8.1. but that version is no longer available online. Any ideas on how to proceed?
