Issues after Proxmox upgrade to Version 8 from 7

[harry.ramanujam@superloop]

Hello Proxmox Team,

I am in the process of upgrading Proxmox from version 7 to 8

However, during the upgrade process, we get the following errors

E: Sub-process /usr/share/proxmox-ve/pve-apt-hook returned an error code (1)
E: Failure running script /usr/share/proxmox-ve/pve-apt-hook

Can someone please investigate these errors and advise on the possible fixes ?

Regards,
Harry
