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?
