I'm trying to upgrade my PVE from 7.14-16 to 8. But in the first step, it shows an error. After I use the command pve7to8 -full, there is an error showing Found mixed old and new package repository suites, fix before upgrading!. Does anyone know how to solve this? I searched online but with no answer.002.png
 
Your /etc/apt/sources.lists.d/backports.list contains a reference to buster, which was used by Proxmox 6. Either change it to bullseye (Proxmox 7) or remove it. It's probably from using a backported piece of software from when you were running Proxmox 6.

Thx, just found it and disable that.
