Hey, I just rented a Hetzner Cloud server. Now i am trying to install Proxmox. Hetzner doesn't have a direct ISO, but they have instructions on how to install it.

when running the Final apt install command, for a while everythung runns Smoothly, untill 77%. Then it Just stopps. The last Messages are:

Code:
Installing new version of config file /etc/default/networking

network config changes have been detected for ifupdown2 compatibility.
Saved in /etc/network/interfaces.new for hot-apply or next reboot.

Reloading network config on first install
warning: duplicate interface lo found

What to do in this situation? When I abbort the process, it fill not boot anymore
 
I have new Infos, this time I aborted the process and killed all processes with a lock on dpkg.
when running "dpkg --configure -a" It also stopps when setting "upifupdown2 (3.2.0-1+pmx9)"
Last console log:
Code:
Setting up ifupdown2 (3.2.0-1+pmx9) ...

network config changes have been detected for ifupdown2 compatibility.
Saved in /etc/network/interfaces.new for hot-apply or next reboot.

Reloading network config on first install
warning: duplicate interface lo found
 
Update:
I fixed the "warning: duplicate interface lo found" problem. lo was configured two times in the config. But it still freezes
 
I fixed it.

Hetzner generates a config file in /etc/network/interfaces.d called 50-cloud-init

proxmox doesn't like something inside this config.
in my case, there is a static ipv6, a dns-nameserver and a gateway specified. When uncommenting any of these options, the Server doesn't want to boot anymore
