PBS boot stuck after upgrade to pbs-2

[Sputnik93]

Hello,

I upgraded my dedicated Proxmox Backup to pbs-2 this morning, using this guide: https://pbs.proxmox.com/wiki/index.php/Upgrade_from_1.1_to_2.x

Everything went fine during the upgrade process, but after a reboot, the server is stuck on this line:

[***   ] A start job is running for Network …tialization (10min 32s / no limit)

I do not have the possibility to access a GRUB menu, as this is a dedicated server.

I can however boot a rescue live CD and then chrrot into my pbs system, here are some information :

root@myPublicIP:/var/log# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug enp0s20
iface enp0s20 inet dhcp
root@myPublicIP:/var/log# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

    inet6 fe80::207:cbff:fe04:d48/64 scope link
       valid_lft forever preferred_lft forever

Until this morning, the server was running pbs-1.x (I do not remember the exact version, but it was up to date, so I guess it was latest pbs-1.x) on top of Debian 10. This installation was relatively young (about 1 month) and I did not install anything else than pbs on this box.

Thank you for your help, I would gladly provide any additional information required

I can however boot a rescue live CD and then chrrot into my pbs system, here are some information :

* could you check which version of `ifupdown` and `ifupdown2` you have installed?
* also check https://forum.proxmox.com/threads/a...-initialisation-t-no-limit.90438/#post-396772
(is there /etc/network/if-pre-up.d/wait_for_link_up on the system - if yes - remove it)

finally try replacing the `allow-hotplug` with `auto`

# The primary network interface
auto enp0s20
iface enp0s20 inet dhcp

I hope this helps!

Thank you for your help.

* I have ifupdown2 installed:

root@pbs-box:~# dpkg -l | grep ifupdown
rc  ifupdown                       0.8.35+pve1                    amd64        high level tools to configure network interfaces
ii  ifupdown2                      3.0.0-1+pve5                   all          Network Interface Management tool similar to ifupdown

* There is no directory /etc/network/if-pre-up.d/, here is the list of files in /etc/network and subdirectories:

root@pbs-box:~# find /etc/network/ -type f
/etc/network/interfaces
/etc/network/if-up.d/postfix
/etc/network/if-up.d/bind9
/etc/network/if-up.d/openntpd
/etc/network/if-down.d/postfix
/etc/network/if-down.d/bind9
/etc/network/ifupdown2/ifupdown2.conf
/etc/network/ifupdown2/addons.conf

* As suggested, I replaced allow-hotplug with auto, here is the new /etc/network/interfaces:

root@pbs-box:/# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#allow-hotplug enp0s20
auto enp0s20
iface enp0s20 inet dhcp

After a new reboot, the problem appears the same.
