Installation error for Proxmox 6.2 on Debian Core

[blower-jump]

I do not use the proxmox iso and install proxmox from repo on top of debian 10.
Follow your advices for installation. After install

pve-xdelta3_3.0.11-dfsg-1ubuntu1.zstd.ayufan2_amd64.deb

I repeat

bash pve-6.1-8-diff-backup-addon apply

then came output:

root@intel-server:~/pve-patches# bash pve-6.1-8-diff-backup-addon apply

You should use patch for 6.2 not 6.1-8.
