[SOLVED] GPG error, no public key

[derp]

Hello,

i can't succeed doing an apt-get update on a debian stretch fresh install that i would like to turn into a proxmox server.
Even though the command "wget -O- "http://download.proxmox.com/debian/key.asc" | sudo apt-key add -" worked fine and returned "OK" it still won't let me update, i get "W: Erreur de GPG : http://download.proxmox.com/debian stretch InRelease : Les signatures suivantes n'ont pas pu être vérifiées car la clé publique n'est pas disponible : NO_PUBKEY 0D9A1950E2EF0603"
Thus i can't install proxmox package, so if anyone got a solution?

Thanks
