I found the issue if I create a LXC container clean install set it up to dhcp and start it I first then got no DHCP IPV4 so I Ask a guy at work for search to issue and it was fix by running

root@container-name$ dhclient

this command dhclient I run and get a DHCP IPv4 and works I can get packages from Web so I made a Script bash

---------------------------------------------------------
#!/bin/bash
######################################################
#### WARNING PIPING TO BASH IS STUPID: DO NOT USE THIS
######################################################
# TESTED ON UBUNTU 22.04.2 LTS on Proxmox (LXC DHCP Fix)

if [ `id -u` -ne 0 ]; then
echo Need sudo
exit 1
fi

set -v

clear
sleep 2
dhclient

--------------------------------------------------------


see that this script auto run as service if you got same issue ;)
