Hello
1. Have you updated your repository before trying to install new packages ? (# apt update)
2. Can you ping a nameserver ? (ping 8.8.8.8)

Well apparently there are some difficulties when running pve in virtualbox.
But fortunately there is a Wiki article explaining the necessary steps to get your system running, have you tried it ?

If you plan to have Proxmox VE host its own (nested) virtual machines or containers that are attached to a VirtualBox virtual network (as opposed to running entirely within Proxmox VE's own internal bridged networking) and would like those guests to be able to communicate with the VirtualBox host or with other VirtualBox-hosted (as opposed to Proxmox VE-hosted) virtual machines, you should ensure that the relevant VirtualBox virtual network adapter is permitted to use promiscuous mode.

This is not the default setting! Rather, by default, VirtualBox denies its guest VMs from effectively enabling promiscuous mode. (Its default setting is Deny.) The setting is available from the Network tab in a VirtualBox VM Machine Settings window (Network → Adapter N [where N is the adapter number] → Advanced → Promiscuous Mode) or can be changed via command line with:

This happening because im on virtualbox, on another node my container has internet

Try to disable the firewall on the VM to make other tests. From your VM you can ping the pve and viceversa?
