Proxmox upgrade 8 to 9 now gives apt warnings

[depechie]

I did the proxmox upgrade from 8 to 9, but the end result is that when I now do an apt update I get double entry warnings...



I understand the warning, meaning there are lists files with the same entries, but I do not know what files should be kept or deleted, or altered... ( to be confirm with a correct proxmox 9 version ).



Also no idea how those got created, I would assume due to the upgrade?
Any pointers on how to best fix this?

Hi,
the repositories you need/should have can be found here: https://pve.proxmox.com/wiki/Package_Repositories
Note that the .sources files are using the deb822 format that is the new standard in Debian. You can simply remove the older .list files if you already have configured the same repository in a .sources file. You should also not need the repository for the beta anymore.
