on my upgrade path (https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0)
i got the error/Warning below --
i just have a singel Server with a couple of VM running.
What is the meaning of the warning, should i really remove proxmov-ve?

so my
# vi /etc/apt/sources.list
1 deb http://ftp.ch.debian.org/debian buster main contrib
2 # deb http://download.proxmox.com/debian buster
4 # security updates
5 deb http://security.debian.org/ buster/updates main contrib
7 deb http://packages.icinga.com/debian icinga-buster main
8 deb-src http://packages.icinga.com/debian icinga-buster main


The proxmox repo is not correct, change to:
deb http://download.proxmox.com/debian/pve buster pve-no-subscription

Or if you have a subscription then activate it so that the enterprise.proxmox.com repo can be accessed
