No network connectivity after Fresh Proxmox 8 install

[and7ey]

I've just installed fresh proxmox 8 (proxmox-ve_8.0-2.iso) on my mini PC (firebat t8 plus), but it doesn't see wired network.

See attached output of some commands. Sorry for photos - can not copy the text or make screenshots, since there is no connection.

The bridge vmbr0 is up and has a link-local IPv6 address. It should be reachable from the LAN.
There are no other IP addresses configured on vmbr0, you may want to fix that by editing /etc/network/interfaces.

Thanks for your help. Is there any way to get its IP4 address? When started, it says `connect to https://0.0.0.0:8006`. My router doesn't see the device connected.

/etc/network/interfaces is attached:

auto lo
iface lo inet loopback


iface enp1s0 inet manual


auto vmbr0
iface vmbr0 inet static
    address 0.0.0.0/0
    gateway 0.0.0.0
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0


iface enp3s0 inet manual


iface wlp2s0 inet manual

I wanted to use DHCP (and assign static address on my router).

You need to enter the actual address with netmask and the default gateway there instead of 0.0.0.0

I replaced

auto vmbr0
iface vmbr0 inet static
    address 0.0.0.0/0
    gateway 0.0.0.0
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0

with

auto vmbr0
iface vmbr0 inet dhcp

but it didn't help. Can not I use DHCP?

No, Proxmox does not have a DHCP client installed. It uses statically assigned IPs as the IP cannot be changed easily after a cluster has been created.
