After upgrade to new version,I can't obtain ipv6 dhcp address again.How do it in the 9.0.11?

I try setup /etc/network/interfaces :
iface vmbr0 inet6 dhcp

Problem still exists.
I try use dhclient -6 vmbr0 and success.
I setup ipv6 address static

Code: 
iface vmbr0 inet manual
        address 192.168.3.86/24
        gateway 192.168.3.1
        bridge-ports enp6s0
        bridge-stp off
        bridge-fd 0
        mtu 9000
 
Install "apt install isc-dhcp-client" should fix it.

Thread 'Proxmox 9.0.4 doesn't get IP by DHCP'

After changing /etc/network/interfaces on a fresh install to:

iface vmbr0 inet dhcp

and running ifreload -a I'm receiving an error message:

vmbr0: cmd '/sbin/dhclient -pf /run/dhclient.vmbr0.pid -lf /var/lib/dhcpdhclient.vmbr0.leases vmbr0' failed([Errno 2] No such file or directory: '/sbin/dhclient')

Indeed there is no file 'dhclient' in /sbin forlder.

Strangely enough it looks like the installer runs DHCP client to pick the IP bound to MAC address up but makes it static.

It worked for sure on version 8.3 or 8.4. But not with v9. Can anyone help please?

Thanks for you help.I already install it but no ipv6 address assigned.

I current add a script use cron at boot to fix this issue.But I want a simple solution.
Code: 
#!/bin/bash
until ip link show vmbr0 | grep "state UP" > /dev/null; do
        sleep 1
done
sudo dhclient -6 vmbr0
