Hi,

I am on stretch and Proxmox 5.4-13 at OVH

After a kernel update and after reboot, I have this error :
Bash: 
root@opale:~# /etc/init.d/networking restart

When i do :
Bash: 
root@opale:~# ifup --ignore-errors vmbr0

Waiting for vmbr0 to get ready (MAXWAIT is 2 seconds).
RTNETLINK answers: File exists
RTNETLINK answers: File exists
It work temporary.

Do you have an idea, please ?
