This problem occurred because we are free user without proxmox enterprise subscription and this prevent us from update or install new package. Here’s how to fix it.

1. Comment out proxmox enterprise source.

root@proxmox:/# vim /etc/apt/sources.list.d/pve-enterprise.list

#deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise

2. Add new proxmox source. Delete old one and put in new source.

root@proxmox:/# vim /etc/apt/sources.list

deb http://ftp.debian.org/debian buster main contrib
deb http://ftp.debian.org/debian buster-updates main contrib

# PVE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve buster pve-no-subscription

# security updates
deb http://security.debian.org buster/updates main contrib

3. Update new source list.

root@proxmox:/# apt-get update
