PVE 8 on Bookworm, ifupdown2 fails

[Daniel Berteaud]

Hi. 

I just installed PVE8 on top of a Debian Bookworm install (unfortunatly, IPMI access on my OVH server is not working, so I had to go with Debian first). 

Most of the installation went fine, except a few minor issues (like : I had to create /run/network dir manually, as ifupdown2 would fail its installation and prevent some other package to install) 

Anyway, now most things are working, except I cannot update network configuration (nor can I apply SDN changes). If I run ifreload -a I get 

root at maurice:~# ifreload -a 
error: name 'traceback' is not defined 
root at maurice:~# 

My /etc/network/interfaces has nothing fancy 

auto lo 
iface lo inet loopback 

auto eno1 
iface eno1 inet static 
address 10.99.0.10/24 
gateway 10.99.0.1 

iface eno2 inet manual 

auto vmbr1 
iface vmbr1 inet manual 
bridge-ports none 
bridge-stp off

post-up echo 1 > /proc/sys/net/ipv4/conf/vmbr1/proxy_arp

auto vmbr0

bridge-vlan-aware yes 
bridge-vids 2-4094 

source /etc/network/interfaces.d/* 

Anybody already had this error ?
