mmm, this is strange, ifupdown2 is creating the directory at service
start


/usr/share/ifupdown2/sbin/start-networking:	[ ! -e /run/network ]
&& mkdir -p /run/network &>/dev/null

seem to be a missing python lib

(just to be sure , what is the output of "ifreload -a -d" ) ?


python3 is installed right ?

dpkg -l|grep python ?




(maybe the /run/network is not created, because ifupdown2 is crashing)

(also, do you have installed ifupdown2 after configuring the proxmox
repos ? just to be sure it's installing the proxmox ifupdown2 version,
and not the debian version)

debug: lo: up : running script /etc/network/if-up.d/resolved
info: executing /etc/network/if-up.d/resolved
error: name 'traceback' is not defined

mmm, it seem to have because of this script "/etc/network/if-
up.d/resolved"


not sure, do you use systemd-resolvd or something like that ?


can you try to remove it ?  (and before, can you send the content of
this file ?)

yep, proxmox don't use systemd-resolvd.

But I think the traceback is a bug in ifupdown2.

It's used to log debug info, but maybe the module is not yet loaded
when the scripts in /etc/network/if-up.d/ are exec.

I think I have seen a report about traceback on the forum some days
ago.

I'll try to reproduce on my side, maybe if the traceback is fixed,
ifupdown2 will simply skip the error and continue.


Thanks for the report !

Re: [PVE-User] PVE 8 on Bookworm, ifupdown2 fails

[DERUMIER, Alexandre]

ok, was able to reproduce with a segfaulting script

this patch should fix it:

https://github.com/CumulusNetworks/ifupdown2/pull/267/files


adding import traceback  in /usr/share/ifupdown2/ifupdown/scheduler.py
